kyc Posted September 9, 2005 Share Posted September 9, 2005 Happens here too. It's only midly irritating but I'd rather it not do that... confuses the heck out of me when I check the time on the taskbar sometimes. Link to comment Share on other sites More sharing options...
macgirl Posted September 9, 2005 Share Posted September 9, 2005 Believe me, people, if you use search first... known issue, put one of your clocks with GMT. OS X with your Time Zone and XP on GMT or OS X with GMT and XP with your Time Zone, deal done. Link to comment Share on other sites More sharing options...
ocstony Posted September 9, 2005 Share Posted September 9, 2005 me 2. But quite strange. I am using completely two harddisks. I will take away one hardisk if booting another os. The time will be nine hours behind. Link to comment Share on other sites More sharing options...
Zeph Posted September 9, 2005 Share Posted September 9, 2005 The OS will Sync with the PC's RTC I wouldve thought. Link to comment Share on other sites More sharing options...

OS X with your Time Zone and XP on GMT or OS X with GMT and XP with your Time Zone, deal done. <{POST_SNAPBACK}> I set XP on GMT and Mac on my time. Restarted to both OS. XP time is stilled borked. But still set to GMT. I tried to go the other way and set Mac to GMT but I can't find GMT in Mac . I'm going to pst a trouble ticket over at Apple. I hope they can solve this problem Link to comment Share on other sites More sharing options...
grimy Posted September 10, 2005 Share Posted September 10, 2005 I think it has something to do with our hardware is missing the PRAM that macs have, i am guessing that the motherboards in the developer macs may have a PRAM area for storage of that info.

phoebus Posted September 10, 2005 Share Posted September 10, 2005 The problem is that MacOS, like many Unices, assumes that the RTC time and date is UTC, aka Greenwich Mean Time. Windows instead always assumes that it's local time. So if you don't live in Greenwich or in the same meridian you get the problem. One solution could be to program both windows and macos to synchronize with a ntp server at startup, if there is a permanent net access of course.

The problem is, I haven't found a way for windows to check the NTP server at boot. We can however use a 3rd party application to run a check during the startup sequence but thats just more applications that needs to be installed just because Windows Time check doesn't collect the time when you reach your desktop.

domino Posted September 12, 2005 Share Posted September 12, 2005 Well see, there is something I do not understand. I can set a handfull of city/country as GMT. Hell, I can even set a country in SE Asia as GMT. I know there is something i'm missing here. Link to comment Share on other sites More sharing options...
skn Posted October 10, 2005 Share Posted October 10, 2005 Hi guys! I found out the answer to instruct WinXP that the Real Time Clock (RTC) runs in Universal Time: http://www.cl.cam.ac.uk/~mgk25/mswish/ut-rtc.html All you have to do is create the following registry entry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation\RealTimeIsUniversal and set it to 1. Have fun! Link to comment Share on other sites More sharing options...
DrJägermeister Posted October 10, 2005 Share Posted October 10, 2005 For german guys (2 hours difference between OSX & Suse Linux): put your OSX time zone to Island until Germany and you'll have the same time in Linux & OSX Link to comment Share on other sites More sharing options...
