海外TECH	DEV Community	A Guide to Handling Date and Time for Full Stack JavaScript Developers	https://dev.to/ddmytro/a-guide-to-handling-date-and-time-for-full-stack-javascript-developers-17i2	A Guide to Handling Date and Time for Full Stack JavaScript Developers Table of contentsIntroductionDate formatsTime zonesUnix timestampThe Date objectCalculating the difference between datesFormatting the dateTime zone on the back endStoring dates in the databaseConclusionUseful resources IntroductionTime plays an essential role in our lives Therefore as developers we get to work with date and time quite frequently Computer software is used by people from anywhere in the world and the time in one region can differ from the time in another region And generally in the software we build we capture and process the date and time of various data records and events Therefore it s important to understand various nuances around working with date and time Date formatsDate and time can be represented in many different formats In Ukraine the date is usually written in the format DD MM YYYY the day is first while in the United States the common format is MM DD YYYY the month is first Time zonesDepending on the geographical area or a political unit e g a country the time zone can differ For example in the summer while in Kyiv the time is in New York the time is minus seven hours Also it s important to mention that the time zone choice definition in a particular country region may be affected by a political decision A country can choose a UTC offset that differs from that country s actual georgraphical location s UTC offset All time zones are defined as offsets to Coordinated Universal Time UTC ranging from UTC to UTC The geographical reference point for UTC is the prime meridian longitude ° that runs through the Royal Observatory in Greenwich London United Kingdom Additionally in various regions of the world people practice Daylight Saving Time DST or in other words summer time This is the practice of turning the clock forward one hour from standard time during the warmer months in order to get more daylight during the hours we re usually awake For example in Ukraine we turn the clock forward one hour on the last Sunday of March at and we return back to the standard time turning the clock backward one hour in the last Sunday of October at The date and time DST starts and ends depends on a country or a political unit e g European Union Also a political region s time zone offset and or the date and time when the DST starts and ends could have been changed at some point in history Therefore there is a number of databases where the information about the time zone changes is tracked The most popular one is IANA Time Zone Database also known as tz or zoneinfo Operating systems and other computer software use these databases for time zone processing and conversions Unix timestampA common format to represent date and time values in computer programming is the Unix timestamp which is a number of seconds between the Unix epoch January UTC and another date e g Positive integers represent the dates after the Unix epoch while negative integers represent the dates before the Unix epoch The Unix timestamp is one of the common formats for storing date and time in operating systems and databases Learn more about the Unix timestamp on Wikipedia Unix time The Date objectFundamentally a JavaScript date is specified as the number of milliseconds from the January UTC This number looks similar to the Unix timestamp The difference is that the Unix timestamp is the number of seconds since the Unix epoch while in JavaScript it is the number of milliseconds In JavaScript we use the Date object to work with date and time const date new Date The Date object holds the current date and time in UTC internally However by default when we output the date and time the Date object converts the output to the local time zone the time zone of the environment where the JavaScript code is running e g a browser Node js etc When instantiated without parameters the date object holds the current date and time new Date holds the current date We can set the date and time in the Date s constructor or after the instantiation let currentDate new Date let someDate new Date December let someDate new Date T let someDate new Date Month s index is zero basedlet someDate new Date Number of milliseconds from Jan UTCWhen we instantiate the Date class the specified date is converted to and tracked in UTC internally However when we access the date using the basic methods e g toString toLocaleString getHours etc the date is returned in the local time zone const myDate new Date May UTC console log myDate Tue May GMT Eastern European Summer Time console log myDate getHours not as you might have expectedHere we instantiate the Date class specifying the date in UTC but when we print the instantiated date object we get the date in the local time zone which for me is UTC Eastern European Summer Time So the date is stored in UTC internally but when we access the date using the basic methods it s converted to the local time zone The most popular methods of the Date object are Date now number of milliseconds since the Unix Epochnew Date getTime sameDate UTC number of milliseconds since the Unix epoch until the specified dateconst dateBasedOnUTC new Date Date UTC const date new Date Access and modify the date based on local time zone date getFullYear for example date setFullYear date getMonth zero based month index date setMonth date getDate day of the month date setDate date getHours date setHours date getMinutes date setMinutes date getSeconds date setSeconds Access and modify the date based on UTC date getUTCFullYear date setUTCFullYear date getUTCMonth date setUTCMonth date getUTCDate date setUTCDate date getUTCHours date setUTCHours date getUTCMinutes date setUTCMinutes date getUTCSeconds date setUTCSeconds Other useful methods date toISOString Get the date string in simplified extended ISO format ISO date toLocaleString uk timeZone UTC Get the date string in the format according to a given locale and various optionsdate toLocaleString en month long Get the name of the month in a given locale e g June July etc Learn more about the Date object on MDN Web Docs Date Calculating the difference between datesconst date new Date Date UTC const date new Date Date UTC const diffInMilliseconds date date const diffInHours diffInMilliseconds console log diffInHours Here we create two date objects May and May Then we subtract May date from May date and get hours of difference When you work with date objects take into account the time zones these date objects were instantiated with Check another example const date new Date T Z ISO stringconst date new Date May UTC const diffInMilliseconds date date const diffInHours diffInMilliseconds console log diffInHours or Here the answer is because the time zone of date is UTC while the time zone of date is UTC Let s see what happens in more detail We set date to May UTC using the ISO format We specify the UTC time zone using the character Z We could specify the time zone using an offset as well like this T is UTC We set date to May using another date and time format with the time zone offset UTC or UTC Then we subtract date from date date date When we use a mathematical operation on an object JavaScript converts the object to a number using the object s valueOf method if it s present In the case of the Date object the valueOf method returns the date and time as the number of milliseconds since the Unix epoch which is a UTC based date and time representation So date has been set in UTC while date has been converted to UTC from UTC So actually we subtract May UTC date from May UTC date and that s how we get for the result Formatting the dateOne way to format a date is to use the getter functions like getFullYear getMonth getDate etc For example to create the date and time string in local time in the format YYYY MM DD hh mm ss we can do the following const date new Date const year date getFullYear const month date getMonth getMonth returns a zero based index of the month const day date getDate const hours date getHours const minutes date getMinutes const seconds date getSeconds const addZero num gt num padStart const formatted year addZero month addZero day addZero hours addZero minutes addZero seconds In order to get the date and time values according to UTC we can use the UTC based getter functions like getUTCFullYear getUTCMonth getUTCDate etc Furthermore we can get the date and time string from the Date object formatted according to a given locale and various options using the Date s toLocaleString method new Date toLocaleString uk new Date toLocaleString en month long Maynew Date toLocaleString en month long day numeric year numeric May Please note that if you don t specify the time zone in the options toLocaleString will output the date in the local time zone new Date toLocaleString en timeZoneName short include the time zone name AM GMT GMT is my local time zone new Date toLocaleString en timeZoneName short timeZone Europe Amsterdam PM GMT First we instantiate the Date object with the local time zone and get the localized date and time string When the Date is instatiated the date and time value is converted internally from the specified time zone or the local time zone if the time zone is not specified to UTC Then we instantiate another Date object with the local time zone This time we set the timeZone option to Europe Amsterdam according to IANA Time Zone Database Therefore we get the localized date and time string based on the Europe Amsterdam time zone In more detail my current time zone is UTC so the Date object is instantiated with the date and time UTC which is converted to UTC internally and becomes Then the toLocaleString method converts this date from UTC to Europe Amsterdam and the result is PM GMT The resulting offset is because it s the Daylight Saving Time offset of the Europe Amsterdam time zone Time zone on the back endUsually computer software e g Node js databases etc by default uses the system date and time configuration Therefore make sure that all the servers that belong to your app use the same time zone UTC is commonly used In Linux you can check the time zone using one of the following commands datedate Z z timedatectlTo change the system time zone you can use the following commands Check available time zone namestimedatectl list timezones Set the time zonetimedatectl set timezone Europe AmsterdamTo check the time zone of the Node js process node e console log Intl DateTimeFormat resolvedOptions timeZone In Node js you can set the time zone using the TZ environment variable TZ UTC node e console log Intl DateTimeFormat resolvedOptions timeZone UTCIf the TZ variable is not set Node js will attempt to use the operating system s time zone Storing dates in the databaseUsually web applications are available from anywhere around the world This means that if we store dates in the database we need to make sure that we store all dates in a single consistent time zone or at least track the time zone of the dates we store Various databases have their specifics as to how they treat date and time values So in this section I d like to briefly explain how to store the date and time values in different databases and mention some of those specifics Usually software especially web apps serves users from all over the world Each user s local time depends on their location For example for the user from Kyiv the local time in the summer is and at the same time for the user in Amsterdam the local time is Basically we should convert and store the dates in a unified time zone usually developers store the dates in UTC So before storing a date we should convert it from local time to UTC For example a user from Amsterdam creates a reminder in a calendar app The user selects the date and time of the reminder in local time Europe Amsterdam time zone UTC standard time and UTC DST Let s say the user sets the reminder date to May using a calendar widget Now before we store this date in the database we should convert it to UTC and the date becomes May in UTC because Daylight Saving Time in Amsterdam UTC became active on March at Luckily we usually don t have to deal with the time zone conversion logic because it s usually built into the programming language and software e g a database we use For example in JavaScript we can get the current date and time in UTC using the Date object new Date getTime number of milliseconds from Unix epochnew Date toISOString ISO date string in UTC MySQLIn MySQL the dates are usually stored using the DATETIME and TIMESTAMP column types MySQL TIMESTAMPMySQL converts TIMESTAMP values from the current time zone e g the global time zone or the client session time zone to UTC for storage and back from UTC to the current time zone for retrieval MySQL doesn t do this with the other column types like DATETIME So TIMESTAMP values are converted to UTC for storage but when they are retrieved they are converted to the current time zone SELECT SESSION time zone Please check this example CREATE TABLE timestamp test id INT NOT NULL PRIMARY KEY AUTO INCREMENT created at TIMESTAMP NOT NULL Set the current time zone to UTC SET time zone SELECT SESSION time zone INSERT INTO timestamp test created at VALUES SELECT FROM timestamp test ORDER BY id ASC id created at Set the current time zone to UTC SET time zone SELECT FROM timestamp test ORDER BY id ASC id created at As of MySQL we can add the time zone offset when inserting TIMESTAMP and DATETIME values into a table SET time zone INSERT INTO timestamp test created at VALUES SELECT FROM timestamp test ORDER BY id ASC id created at SET time zone SELECT FROM timestamp test ORDER BY id ASC id created at Let s see what happens in this example We set the current time zone to UTC We insert a date value with time zone offset UTC MySQL converts this date and time value from UTC to UTC for storage We select the rows from our table and MySQL converts the TIMESTAMP values from UTC to the current time zone UTC upon retrieval Then we set the time zone to UTC and select the rows again and because MySQL converts the TIMESTAMP values from UTC to the current time zone upon retrieval we get the date we ve inserted earlier in UTC this time The TIMESTAMP type has a range of UTC to UTC MySQL DATETIMEMySQL DATETIME is stored and retrieved as is CREATE TABLE datetime test id INT NOT NULL PRIMARY KEY AUTO INCREMENT created at DATETIME NOT NULL Set the current time zone to UTC SET time zone INSERT INTO datetime test created at VALUES SELECT FROM datetime test ORDER BY id ASC id created at Set the current time zone to UTC SET time zone SELECT FROM datetime test ORDER BY id ASC id created at MySQL does not convert DATETIME values from the current time zone to UTC and vice versa However something interesting happens when we insert a DATETIME value with a time zone offset Set the current time zone to UTC SET time zone Insert a date with the time zone offset UTC INSERT INTO datetime test created at VALUES SELECT FROM datetime test ORDER BY id ASC id created at In the example above we can see that when we insert a DATETIME value with a time zone offset MySQL converts this date value to the current time zone for storage current time zone offset The DATETIME type has a range of to To store a date and time value I d convert the local date and time value to UTC in the application code and store this value in the DATETIME column Basically I d handle the time zone conversion on the application side and store all dates in UTC I d use DATETIME instead of TIMESTAMP because TIMESTAMP is actually a bit integer and doesn t allow to store dates beyond UTC while DATETIME allows us to store dates up to PostgreSQLIn PostgreSQL we usually store date and time values using the column types timestamp without time zone or simply timestamp or timestamp with time zone or simply timestamptz Both types have a range of BC to AD PostgreSQL timestamp without time zoneThe timestamp without time zone values are stored and retrieved as is CREATE TABLE without time zone id SERIAL PRIMARY KEY created at TIMESTAMP NOT NULL INSERT INTO without time zone created at VALUES SELECT FROM without time zone ORDER BY id ASC INSERT INTO without time zone created at VALUES SELECT FROM without time zone ORDER BY id ASC In this example we create a timestamp without time zone column called created at And we can clearly see that the date and time value is stored and retrieved from this column as is If we specify the time zone the time zone is ignored PostgreSQL timestamp with time zoneThe timestamp with time zone timestamptz values are converted from the specified time zone to UTC If you don t specify the time zone when inserting a timestamptz value PostgreSQL will assume that this date value is based on the current time zone SHOW time zone CREATE TABLE with time zone id SERIAL PRIMARY KEY created at TIMESTAMP WITH TIME ZONE NOT NULL Set current time zone for the session to UTC SET time zone SHOW time zone lt gt INSERT INTO with time zone created at VALUES SELECT FROM with time zone ORDER BY id ASC INSERT INTO with time zone created at VALUES SELECT FROM with time zone ORDER BY id ASC What happens in this example is the following We create a table with a column called created at which has type timestamp with time zone We set the current time zone for the session to UTC Please note that in PostgreSQL we can specify the current time zone using an integer offset or the time zone name e g America New York To get a list of supported time zone names query the pg timezone names table SELECT FROM pg timezone namesWe ensure that the time zone offset has been set properly We insert a row with the created at value of into the new table Because created at column has type timestamp with time zone PostgreSQL converts the date value from the specified time zone in our case to UTC for storage So the value that has been actually stored is We select the inserted row from the table and the date value is converted from UTC to the current time zone offset which is UTC We insert another row into the table but this time without specifying the time zone offset If we don t include a time zone offset PostgreSQL assumes that the date value we provide is based on the current time zone which in our case is UTC So before storing this date value PostgreSQL will convert it from the current time zone UTC in our case to UTC and the following date value will be stored UTCFinally we select all rows from our table again and see that the date value we ve just inserted is displayed in the current time zone To store a date and time value in PostgreSQL I d use the timestamp with time zone timestamptz type Basically I d choose timestamptz instead of timestamp because of the reasons mentioned in the following article from the PostgreSQL Wiki Don t Do This Date Time storage DynamoDBYou can use the string and number data types to store dates and timestamps We can use the string data type to store date and time values in ISO format e g T Z And we can use the number data type to store date and time values as UNIX timestamps Epoch time a number of seconds since January UTC This will allow us to sort and query items by date and time MongoDBIn MongoDB internally dates are stored as bit signed integers representing a number of milliseconds since the Unix epoch January UTC Negative values represent the dates before the Unix epoch To insert a date in the Mongo shell we can use the Date object Specifying the current date and time value when inserting an item db books insertOne title Book createdAt new Date db books find id ObjectId acdffde title Book createdAt ISODate T Z You can pass an ISO string or a number of milliseconds since the Unix epoch into the Date constructor new Date new Date T Z new Date If you specify a time zone offset the

in Now let s start the article Developing amp Selling a SAASNext up we have the first one on the list is SAAS development and selling Now what is a SAAS Well It stands for software as a service some famous examples of a SAAS are Microsoft Office Excel Word AWS Dropbox etc Although developing a SAAS is not an easy thing at all you are gonna need tons of research and development needs to be put in to even have a profitable SAAS but if you re able to deliver a product to the world you can make an impressive passive income Here is a basic layout of how a SAAS is created software is created gt website storefront is created gt user buys uses SAAS from website gt SAAS owner is paid You really only need to create the SAAS and the website after that the sales are pretty much passive but time must be spent on managing and updating the SAAS You can check Vuexy Vuejs Admin Template for example Vuexy Vuejs admin template is one of the most developer friendly admin templates It is multipurpose highly customizable and responsive You can use Vuexy Vuejs React Angular HTML amp Laravel Admin Template for any kind of web applications such as eCommerce educational fitness etc Mobile App Game DevelopmentThis next one is a very popular option for a lot of people Mobile app game development is an ever growing industry Similar to a SAAS you ll have to put in the work to develop the app game but all of the income is essentially passive Some of these passive income ideas from an app or game could be mobile ads game sales in game app sales etc There are endless possibilities in this sector if you have some knowledge of mobile game app development you can make some very powerful passive income streams Create a Video Course Becoming a Coach Well video tutorials are always in demand if you are good at explaining things in detail then this option is worth trying Now at this point in time there are actually more positions for skillful programmers than there are people to fill those positions With that in mind it is easy to conclude that programming is in incredibly high demand right now and will be for years to come With that much demand not only can you make money through programming but also you can make money teaching programming There are literally hundreds of thousands of people in the world who want to learn what you already know And if you are a talented teacher this could be an excellent side income for you You can literally teach programming to anyone in the world It s is a HUGE market Platforms like Udemy make it super easy to create your courses and make money from them All you need to do is create a high quality course They will take care of the marketing and everything else Creating Articles CoursesThis is one of the best ways to make passive income as a programmer right now You can spend some time developing an article post it and forget about it the article will then continue to garner revenue forever as long as it gets views reads without spending much time on it anymore Courses are another great way to develop income I would definitely say a course takes more effort to develop but I have heard courses are very lucrative as well From all of the passive income sources this one is probably the best way You can start as a writer on platforms like medium dev to etc Building an audience will eventually help you Web HostingNext up we have web hosting this is a bit different than website development Web hosting is essentially storing a website on a server thus the website is able to be accessed anywhere online these websites will be renting server space from you Some very popular web hosting websites are Hostgator Siteground and Bluehost you would essentially be creating your own web hosting service Buying a Profitable WebsiteThis one is one of the best ways to have a passive income This is more of an investment that can lead to passive income You have to choose a website that allows you to sell and buy websites applications you ll be also able to get income reports from the websites as well Let s say you didn t want to develop an application right now well you could just buy an existing application and profit off of that specific investment This one doesn t really require massive amounts of programming knowledge but if you plan on updating the websites applications it could totally help by understanding the programming languages around those products Finding BugsIt is a well known fact in the web development world that Software failures are a genuine problem for companies economies They
