buzlink Posted May 16, 2007 Share Posted May 16, 2007 What settings do I need to set to allow for my system clock to report the correct time, in both OS X and Vista? Thanks Link to comment Share on other sites More sharing options...
Tick-Tock Posted May 25, 2007 Share Posted May 25, 2007 The clock in OS X should automatically update itself, the same goes for the Windows clock. In both OSes, click/double-clicking on the clock will bring up the date and time settings, and from there you should be able to tell it to auto-update from the internet, if it's not doing so already.

Synaesthesia Posted May 25, 2007 Share Posted May 25, 2007 No, I have the same problem, as do many ppl. The two os'es are out of sync. I will have to trawl the forum a bit for a potential solution. Link to comment Share on other sites More sharing options...

roboman Posted June 10, 2007 Share Posted June 10, 2007 for some odd reason I cannot change my clock. Whenever I do it sets itself back 4 hours meaning if its actually 11:00pm it sets to 7:00 pm automatically and I have chosen Miami, FL for timezone. This is really weird because if I go reboot into Windows XP its the same.... Link to comment Share on other sites More sharing options...
nikg_v1 Posted July 22, 2007 Share Posted July 22, 2007 To my expierience, XP does update to the correct time, but OSX doesn't. I have them both set to auto update. Link to comment Share on other sites More sharing options...
tokyovigilante Posted August 5, 2007 Share Posted August 5, 2007 No, I have the same problem, as do many ppl. The two os'es are out of sync. I will have to trawl the forum a bit for a potential solution. The problem is that OS X (like most *nixes) sets your system clock to UTC and then applies your local time offset to show the correct local time. Windows (XP and Vista) store it as local time. There was a registry key you could set in XP to store as UTC, but I don't know if this works in Vista. As mentioned by others, getting both OSes to use NTP to update is the best workaround for now.

Sub Posted October 24, 2007 Share Posted October 24, 2007 I found this solution on a forum posted by "josmul123" here *** WARNING: Editing your registry improperly can render your Windows installation inoperable. Proceed VERY carefully. I am not responsible if you mess something up. *** The short solution for people who know how to edit the registry: A DWORD key called HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSetControl\ TimeZoneInformation\RealTimeIsUniversal needs to have the value of "1" The step-by-step solution is as follows: 1. Boot Windows 2. Click Start --> Run and type regedit. Click OK 3. The Windows Registry Editor should pop up. Navigate within the explorer to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet then to: Control\TimeZoneInformation 4. Click on the TimeZoneInformation "folder" from the navigation pane if you haven't already done so. 5. This assumes the correct key doesn't exist. If it does, you will just change the existing key's value: Right click on the white space within the folder (If you don't have a right mouse button, you may need to download a program called applemouse to emulate the "control-click" of the apple 1-button mouse). Select new --> DWORD Value. Title the key "RealTimeIsUniversal" (No quotes). Set the value to "1" (No quotes again). Hexidecimal should be fine. 6. Either reboot and set the clock in MacOS or set the clock in Windows. You should now be able to reboot into either OS and have a correct clock.
