I am working on a C# project in which user can change datetime column time zone using its profile page. For example, when I log in into the system, I can change default time zone (PST) to Indian standard time(IST) after doing all the column of date time should show time-related to IST time zone.

Basically, we are saving all the datetime value in the database as PST time zone, now based on user-selected time zone I need to show datetime.

So I would like to convert my PST datetime (8/16/2016 12:56 PM) to IST or any other timezone selected by user dynamically using C#.

How can I convert datetime from PST to any time zone using C#?
