I have a DateTime stored in universal time (UTC) of value 2010-01-01 01:01:01.
I would like to display it in EST in this format 2010-01-01 0
I think you are looking for the TimeZoneInfo class (see http://msdn.microsoft.com/en-us/library/system.timezoneinfo_members.aspx). It has many static methods to convert dates between time zones.
