I have iAtkos v7 upgraded to 10.5.8 running on one HDD, and Vista Ultimate 64-bit running on another HDD. I choose which one to boot from during my bios post screen. It works great.

My only problem is that if I set the time correctly in OS X, it's off by 7 hours in Vista. OS X reads 9:45am, Vista reads 4:45pm. And the same goes for the other way around. If I set the time to be correct in Vista, it's off by 7 hours in OS X. Both OS's are set to the same time zones.

How can I correct this so both systems display the same time?

The only thing I can think of, is set one of the OS's to GMT 0, and see if that fixes it.

Field Note #1 @thorazine74 2009-09-20

Google for appletimeservice for a possible solution.
There's also a registry hack to make vista use utc instead of local time.

Field Note #2 @zuz242 2009-09-20

there is a timefix package for osx by zeph, incorporated in most distros i used.
it must be found somewhere if googled. try "localtime-toggle.pkg"
