I need to display times for 6 locations around the world on a local server, including the current time where the web server sits.
I also need to adjust for DST.

Is there a straight-forward way of doing this?

Here's a link to info about 'tzdata', a public domain time info database: http://en.wikipedia.org/wiki/Tz_database   I don't find a link to C# code right off but there probably is sample code somewhere.  tzdata is frequently updated.

I would try to use an existing web service that provides that functionality. There is a free one with sample code here. http://www.csharphelp.com/2006/10/consuming-a-web-service-in-c/

If you only need 6 locations and not the whole world, then maybe this is project will get you started. http://www.codeproject.com/KB/selection/3ZoneWorldClock.aspx

Even with improvements in ASP.NET 3.5, it's this involved?

This 'seems' to be the answer I'm looking for, does not require the larger efforts noted above, and accommodates DST:

Using the .NET 3.5 TimeZoneInfo object:

DateTime oldTime = new DateTime(2007, 6, 23, 10, 0, 0);
TimeZoneInfo timeZone1 = TimeZoneInfo.FindSystemTimeZoneById("Central Standard Time");
TimeZoneInfo timeZone2 = TimeZoneInfo.FindSystemTimeZoneById("Eastern Standard Time");
DateTime newTime = TimeZoneInfo.ConvertTime(oldTime, timeZone1, timeZone2);

Open in new window
