vu sur le forum Apple:
- 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\CurrentControlSet\Contro
l\Ti
meZoneInformation\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\Contro
l\Ti
meZoneInformation
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.
DO NOT USE THIS REGISTRY HACK...many longtime pc users know this will cause problems in the future..i would use the os x timezone fix or the batch file fix above..
bon, comme vous l´avez vu, certains disent que ça peut être dangereux.
en tout cas j´ai testé, et ça fonctionne jusqu´à présent sans problème (juste la première fois que j´ai rebooté sous Mac OS, les prefs date et heure freezaient, mais après un changement d´OS ça ne le fait plus)
