Are you sure it's not for daylights saving time?
its probabaly off an hour because you need to update your OS with the latest daylight saving hotfix from microsoft.

See KB933360 article on microsoft website.
Okay follow these steps, hope they may solve your queries.

1. Double click on the time from your Taskbar.
