I have a standard PC running Windows 7 Ultimate (64-bit). For some reason, it refuses to keep the correct time zone (the BIOS battery is OK) when restarted.
Note (1): The Time zone is correct. The "Internet Time" tab also shows "this computer is set to automatically synchronize with 'time.windows.com'. When I click the 'Change settings...' button, the 'Synchronize with an Internet time server' checkbox is checked.
Still, upon reboot, the time is skewed by 6 hours... and doesn't correct itself even after waiting hours for this "automatically synchronize" to occur.
Note (2): The BIOS time is set to local (i.e. not UTC). When I restart Windows 7 without booting to the other OS installed in dual-boot config (Ubuntu Linux), it seems to correctly remember the time. This may explain immediate time upon reboot, but it doesn't explain why Windows 7 won't automatically 'Synchronize with an Internet time server' even after an hour.
Why is this happening and how do I correct this?
