...setting each system to a different time zone?
I am warning you in advance, please do not ask Why? or But there is no reason? or Who wants to do that? No buts! It seems strange, like who wants to do this, but I do want to do it, so don't ask why. If you know how to solve it, just tell me, even if it is in Regedit or CMD, or if I have to do something with system files. I have System Restore, so if something goes wrong, I will restore my system. As long as it is a fix, please help.
okay, here is the case:
I have three systems they are Windows 7, Windows 8, and Windows Vista. I want all of the systems to have the correct time, except for Windows 7. With Windows 7, I want the date to be the date Windows 7 Beta (build 7000) was released, which is January 9th, 2009, and the time doesn't matter. Yes, I know that time will change as time goes on, it's okay. The problem is, when I enter Windows 8 (or Vista), the time will be set to something different, usually 8 is set to some time in July 2012, and Vista I don't remember. So I change Vista/8's time back to the current time, and then when I restart back into 7, it is back to the current time.
Please tell me how to make them NOT synchronize when I restart!
NOTE:
I will tell you that this is a sort of experiment, but if I can't get the time working, then a bunch of things will get screwed up all at once. The reason of this is private, so don't ask. But if you have a solution, please let me know.
WHAT I'VE TRIED:
1. Disabling time sync with Internet (time.windows.com) in Windows 7's time and date preferences.
2. Disabling Windows Time service on Windows 7
none of those troubleshooting options worked!
