You are confused about timezones ? Too lazy to calculate ? When you are using windows 7 you can add an additional clock.
Here is what I did:
click on Datum und Uhrzeit ändern
click on checkbox : Diese Uhr anzeigen
choose: UTC (Koordinierte Weltzeit)
click OK
Now you can always check what time it is in UTC. It would be nice if someone adds a discription for the english interface
If you need a new server to synchronize your clock you can try this one in Braunschweig/Germany: ptbtime1.ptb.de
For more info about UTC you can also check: http://www.timeanddate.com/worldclock/
