Time/Clock Problems

[A Hamster]

Windows's time is perfect, and when i reboot, and go to mac, its time is right also. But after i reboot and go back to windows, the time is changed and i have to go through the sync-ing the clock. What's up with that and how can i fix it?

OSX and Windows store time differently in BIOS. OSX stores time as UTC (GMT) and then adjusts it with an adder to the local time. Windows stores local time. So they will always be at odds with one another.

 

To get around this, there are 3 ways:

1) Get an app that sets the time off the internet

2) There is a batch script that can be run at startup to reset the time

3) There is a registry key that can be set, but this is an unsupported register and MS may change its behavior at any time, so this is not recommended.

This link takes you to two other links which discuss 2) and 3)

I use the 3rd method and no problem found in XP so far. Thanks!
