So you finally got around to setting getting that copy of Windows out and setting up bootcamp… or… you’ve been running bootcamp forever and you can’t figure out why the stupid clock in windows won’t work. Nothing will sync because the time doesn’t match up with the real time, it’s a mess and you need to do something about it. Here’s a quick fix.
Most of the fixes on the interenet tell you the wrong way. They say to:
Go to the registry editor and navigate to: HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > TimeZoneInformation
and add the key: RealTimeIsUniversal
and add the DwordValue: 1.
Well it turns out that that method doesn’t work. Sure it looks good for awhile, but after an hour the clock goes back to GMT and it’s broken again, the quick fix is to:
- Right click on the desktop
- new -> text document
- sync-clock.bat
the .bat part is important, if you don’t have extensions enabled it will end up being sync-clock.bat.txt and that’s no good. It must be a bat file. - Copy and paste “
w32tm /resync", without the quotes into that bat file. - Save
- Close
- Move that file into the startup folder on the start menu
There, it looks long, but it is really easy. Now Windows will automatically sync with the time servers when you login.
