how to change the time zone configuration of my windows 2003 server from GMT to UTC

how to change time zone configuration of my windows 2003 server from GMT to UTC?

right now the problem is DataSet serialization (DateTime columns) between windows 2003 server and windows 2008 server via .NET Remoting. (.NET Framework 4) they both on the same开发者_StackOverflow中文版 time zone (also same LAN). the 2008 server timezone setting use UTC. the 2003 server timezone setting use GMT.

if i change just for testing only the 2003 server to another 2008 server which use UTC setting, everything work well (there is no problem between 2 2008 servers).

so i think the problem is because one server is GMT and the another is UTC, or may be the 2003 server need time zone hotfix (although the problematics dates are in the past, year 1975 for example).

GMT and UTC are the same thing. All these are the same:

Greenwich Time / Zulu Time / UTC
