Bootcamp Time Resync for Windows XP
Wednesday, October 3rd, 2007Every so often while booted in Windows XP, I notice that the system time is off by 3 hours. This is due to the differences between how Windows and UNIX/OS X read time from the hardware clock, but that’s not important.
To solve it, I created a batch file in Notepad.exe containing one line:
w32tm /resync /rediscover
I saved it as resync.bat to my startup folder (right click Start, open Programs>Startup) and dragged a shortcut to the desktop. Now XP resyncs to the correct time when I reboot, and if it strays I just double click the batch file.
