TimeZone or DST issue in Win7 or IE9?

Question

Does anyone know about an issue with Windows 7, IE9 and time zones and/or DST (Daylight Time Savings)?

I ask, because when we calculate and print the beginning of each month (with javascript) one of our workstations prints the following lines:

2011-10-01 00:00:00 UTC+2
2011-11-01 00:00:00 UTC+2
2011-12-01 00:00:00 UTC+1

but here in Austria, we switch to winter time in october, so on all other workstations it looks like this...

2011-10-01 00:00:00 UTC+2
2011-11-01 00:00:00 UTC+1
2011-12-01 00:00:00 UTC+1

...which is correct.

I already checked many settings of the workstation. Date, Time, Timezone,... everything's configured properly. Any idea?

There was a DST patch released a week or so ago, do a manual windows update on the PC.
Are you sure there isn't a bug in your code? If the settings on all your workstations are the same, that would be my first guess, debug the javascript. The fact only a single workstation does this ( I doubt you have 1 Windows 7 workstation ) also means there is something different about that workstation.
Ughh, Time zones. Yet another strange factor you have to take into when writing an OS. Not disk performance. Not UI design. Not Productivity concerns. But Time Zones.
