The above code is from the package which we have imported and what it does is we have a database of the different type of the timezone from one there is a IANA/Olson Time Zone Database. So, firstly, let's just narrow down the above code to understand more about the conversion functions.

Now, we have unspecified the kind, and we are moving towards getting our windows type time zone. TimeZoneInfo ut = TimeZoneInfo.FindSystemTimeZoneById(TZConvert.IanaToWindows(timezone)) DateTime localDateTime = DateTime.SpecifyKind(localDateTime, DateTimeKind.Unspecified) NOTE: Mostly the Developer uses the ToUnivesalTime() function to convert time to UTC, but it results in inconsistent output if timezone is not same, which basically takes deployed environment's timezone as reference. So, we have to mark the kind as unspecified.

Over here, we have specified this date time as unspecified because we have a timezone we want to convert it to the UTC time with respect to the timezone which we have. This method is used to create a new DateTime object which has the same number of ticks as the specified DateTime but is designated as either local time, Coordinated Universal Time (UTC), or neither, as indicated by the specified DateTimeKind value. localDateTime = DateTime.SpecifyKind(localDateTime, DateTimeKind.Unspecified)

Convert to UTC with Specific Time ZoneĬurrently, we are using the c# for this function, and we can use it as a library as well. Now, let's quickly move on to our solution and what we are going to do over here is we are going to take a current time zone and time and with respect to the timezone we are going to convert it to the UTC time zone to store the time in the database, and we are going to perform the operation on the UTC time zone and at the time of getting the data from the database we are again going to convert it to the current time with respect to timezone.

#Time zone conversion install

I have added two commands, one is with the -Version which is optional if you want to install it with the specific version, and if you want to install the latest package then you can use the first command. Install-Package TimeZoneConverter -Version 5.0.0 To install it with the help of Package Manager Console, Go To Tools → NuGet Package Manager → Package Manager Console and copy the following command and paste it inside the console and install it.And then search the TimeZoneConverter in Browse tab and install it.

To install it with the help of NuGet Package manager, Go To Tools → NuGet Package Manager → Manage NuGet Packages for Solution.

Which we can install directly from the NuGet package manager window or package manager console. Requirementįor this solution, we need to import one package into our project which is TimeZoneConverter. So, here values like the +5:30 and -5:30 are called the offset, and it adds or subtract the hours:minutes based on your conversion with reference to UTC. Now, let's check how it shows the difference, for example, Indian UTC timezone is UTC+05:30 and Canadian UTC timezone is UTC-05:30. Ultimately it becomes the 10 hours and 30 minutes, So, when we compare Indian time with the UTC where India is 5 hours and 30 minutes ahead of Coordinated Universal Time and UTC time with Canadian where Coordinated Universal Time is 5 hours ahead of Ottawa. Now, to show this difference there is a universal timezone which is global timezone that shows the difference in terms of the hours and minute. Like we compare Indian time zone with Canadian time zone where India is 10 hours and 30 minutes ahead of Ottawa for example. So, every country has its own time difference compared to other countries. Now, the question is how does this Time Zone show the difference with different countries, Rrght? so, we can see the difference in the time is defined by the Time Zone Let's say right now in India the current time is 12:59 AM then at the same time in Canada the time is 2:29 AM. The Time Zone has some parameters, one is offset, or we can say a difference between two times in an hour, which you can see in the times for different countries. So, we have to handle the different times for different countries. In this internet world, we don't have any idea which person is accessing our application from which country, and our application doesn't have any idea about the time duration in the device and because of that issue sometimes our application is going to crash or giving an unreliable result to the user. Today we are going to create two functions that make your life easy and handle different times and make your application or web completely dynamic within different time zones.
