BiTRiP Posted August 23, 2009 Share Posted August 23, 2009 Hey folks, Anyone that have the same problem as me, that after I have booted in OSX and I reboot in windows (or other OS) then the time is changed 2 hours earlier. Even the BIOS time is changed! How come and how to fix that? Thnx, BiTRiP Link to comment https://www.insanelymac.com/forum/topic/181198-time-changes-after-osx/ Share on other sites More sharing options...
brlock Posted August 23, 2009 Share Posted August 23, 2009 that happens because OSX sets the BIOS time to GMT and then calculates the screen hour according to your time zone. Windows on the other hand sets the BIOS time to whatever is the time in your time zone. disable the "Set date & time automatically" in OSX and adjust your time zone to gmt. this should work Link to comment https://www.insanelymac.com/forum/topic/181198-time-changes-after-osx/#findComment-1232787 Share on other sites More sharing options...

mr_christer Posted August 24, 2009 Share Posted August 24, 2009 thanks for the hint rod. I had to manually add the key to Windows 7 registry but it works!

BiTRiP Posted August 25, 2009 Author Share Posted August 25, 2009 Adding that key works perfect! With both OS' on auto timesync and right timezone!
