timezone

I have a windows instance up in EC2. I manually set the timezone to Pacific.

1) For some reason using window's built in time sync doesn't work in the instance...but whatever. I turn off automatic time syncing...

but 2) On reboot the time on the server changes! For example, if i reboot it at 4PM on Wednesday, when the server comes back up it will read 12 noon on Thursday!

As a result any access to Amazon's other services like SImpleDB fail because the timestamps generated are too far off the current time.

Has anyone seen this or figured this out?
