Hackintosh partition messes up my clocks...

[taylert123]

I don't know why but whenever I use my hackintosh OS it makes the time on my vista partition incorrect, and when using vista it does the same thing to the hackintosh.

 

Is there someway to fix this? In vista i though I'd probably just do "automatically update time" but no matter what settings I use it seems to think that I'm in the wrong timezone (even though the correct one is listed) and it sets me an hour ahead.

 

How can I fix this?

 

I think this might be cause by how I dual boot. If it matters, I installed OSX, used my vista install DVD to repair MBR, then while in Vista I dled easyBCD. When I boot I have to select OSX in the vista bootloader, then select the correct partition in the darwin bootloader. (if someone knows how I can "quiet" boot or w/e it's called that would be appreciated too)

 

thanks!

When I setup my OSX install I left the time stuff alone and now I have no problems

This is probably a UTC/local time issue. Windows, by default, assumes that the hardware clock is set to local time. MacOS, OTOH, assumes that the hardware clock is set to UTC (aka GMT -- the time in Greenwich, England, unadjusted for daylight saving time). Thus, when each OS saves its time to the hardware clock, the other OS will get messed up.

 

The solution is to reconfigure one OS to use the other's default method. I believe there's a way to have MacOS use local time, but I don't have a reference, offhand. My preferred method is to have all OSes use UTC, if possible. This tends to cause fewer problems around daylight saving time changes, since if all OSes use local time, each OS may try to make a DST change, thus overshooting the mark. In any event, this site has instructions on setting up Windows to use UTC. I've been using this method for at least a year with no problems; however, I seldom boot Windows, so there may be issues that would turn up with more prolonged Windows use.
