If you are not running XP or Vista go to this address:
ftp://ftp.microsoft.com/services/tec...FIG/TZEDIT.EXE
Download the EXE file (direct from Microsoft) when you open it you will be able to manually set your DST parameters. It is supposed to work on all Windows platforms back to 95. I downloaded it for my Win 98Se. I reset my parameters and will see Sunday morning.
