I usually use this site for converting time in different zones. http://www.timeanddate.com/worldclock/converter.html 

This should put you on the right direction. For basic programming purpose you might want to use the GMT as a reference point for other time conversions. GL

The format on the start date time is flexible. But, it has a time and timezone for the start date. I need to convert this to the server's time zone datetime or another time zone.

Now i see what you mean. I guess it will be clearer if you had included that in your question.

Have a look at this blog posts:

the zone asp.net is specified in the questions so I think everyone understands it. oh well, I already looked at these articles and didn't help me. The problem I have is I get this datetime with a timezone so that cannot be changed. I need to convert this to server timezone.

Hi,

Try below code:

DateTime DT = DateTime.ParseExact("09-25-2011 01:00am CET", "MM-dd-yyyy hh:mmtt CET", null);
TimeZoneInfo sourceTimeZone = TimeZoneInfo.FindSystemTimeZoneById("Central European Standard Time");
TimeZoneInfo DestTimeZone = TimeZoneInfo.FindSystemTimeZoneById("Eastern Standard Time");
DateTime DT_EST = TimeZoneInfo.ConvertTime(DT, sourceTimeZone, DestTimeZone);

Open in new window

Thanks rajapandian_81. That is working but just a quick question can it consider daylight saving time as well?
