Looking for a solution to sync time between Mountain Lion and Windows 8. Any help is appreciated.
Thanks,

Set your Windows time to UTC. Copy the following code into a file and save as .reg then open.

Code:
[LEFT][COLOR=#000000][FONT=Arial]Windows Registry Editor Version 5.00[/FONT][/COLOR]

[COLOR=#000000][FONT=Arial][HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation][/FONT][/COLOR]
[COLOR=#000000][FONT=Arial]"RealTimeIsUniversal"=dword:00000001
[/FONT][/COLOR][/LEFT]


After reboot into OS X and your time should stay synced up.

Unfortunately this is not working ATM. MS for some stupid reason has disabled it.

It worked for me when I tried it.

One thing I did notice is you have to set the BIOS clock manually to UTC/GMT because perhaps Win8 is updating the system BIOS clock on some sort of schedule or something, so it doesn't take effect when you set this and sync the clock to an internet time server. Or maybe they are refusing to set BIOS time because they see it as accurate in local time.

But what I found after setting the BIOS time is that in Win8 this option works better than in Win7. In Win7, this option was made almost unusable because any task in Task Scheduler set to wake the computer would not work (evidently they were still doing a conversion to local time when sending the "wake time" down to the BIOS... oops.)

For now, I'm still running Win7 (in multiboot config) so I can't use this option, because I need Win7 tasks working correctly. What I do instead is set OS X to GMT time zone and still have system time set to local time (Pacific). That is not perfect either, I had at least one on-line order be rejected because they thought it might be fraud (server noticed my time zone GMT, but strange time set, and location of credit card acct not in GMT). I think it makes the time of my posts here (for example) look strange.
