c# - Get DateTime For Another Time Zone Regardless of Local Time Zone

Question

Regardless of what the user's local time zone is set to, using C# (.NET 2.0) I need to determine the time (DateTime object) in the Eastern time zone.

I know about these methods but there doesn't seem to be an obvious way to get a DateTime object for a different time zone than what the user is in.

 DateTime.Now
 DateTime.UtcNow
 TimeZone.CurrentTimeZone

Of course, the solution needs to be daylight savings time aware.

Answer 1

In .NET 3.5, there is TimeZoneInfo, which provides a lot of functionality in this area; 2.0SP1 has DateTimeOffset, but this is much more limited.

Getting UtcNow and adding a fixed offset is part of the job, but isn't DST-aware.

So in 3.5 I think you can do something like:

DateTime eastern = TimeZoneInfo.ConvertTimeBySystemTimeZoneId(
    DateTime.UtcNow, "Eastern Standard Time");

But this simply doesn't exist in 2.0; sorry.
