Question : Convert time from localtime to EST

Does anybody know how to convert local time (TDateTime) into timezone EST (US east coast). Preferable using Windows API.

I've checked out the function TzSpecificLocalTimeToSystemTime, but it's not included in Delphi's windows.pas

I'm currently using D2006.
