Set Different Dates On Dual Boot?


I have a multi-boot (10, 7 & XP) system and would like to change the date on 7 or XP to Feb. 2012. Is it possible? With all the utilities out there, surprised I could not find any on line. Thought with virtual-everything these days, there should be a utility to control the date on the other OS. Just checking if it is possible. Will still keep the main OS (Win10) at current date and time (Time Zone).
Thanks in advance.

Windows 7 and Windows XP should both have options in the adjust date and time settings to turn off automatic time setting over the internet. The problem, I believe, is that the operating system also updates the system clock in bios/UEFI. So when you boot into Windows 10, it would change the system clock in bios/UEFI to the current time. Then when you return to Windows 7 or XP, upon booting the OS would read the system clock in bios/UEFI and startup with that date/time setting.

Ditto. If you turn off time sync, and then adjust the time manually, it will likely get set in the BIOS to match. Then on the next boot into Windows 10, it will sync and reset it to the correct time and date. Wash rinse and repeat. Why Feb. 2012?

Time sync has always been a PITA with Dual boots.

Looks like you miss-read my message. I do NOT want it to "sync". I would like Win10 to be correct time and date and XP to maintain (unsync) amd maintain and start from February 2012. Guess it is not possible since you mentioned the BIOS system time control.

You might be able to create a powershell script or bat file that runs upon booting which resets the date/time to what you want.

Yep. That's what I am looking for. A bat file or a utility to install. Can't write scripts for OSs. Just wondering if anyone has come across such. Thanks though.

I believe the bat file command for setting the date would be:

date 02-01-2012

The format is date mm-dd-yyyy

Did not misread anything. This problem has been long going with Dual boot aystems not having one OS installed sync properly, since the bios clock is affected by the first OS booted up forthe day.

Been doing this for over 30 years and the UTC problem can only be solved if you force a clock update when logging into the OS.

Clock is physical/electronic device. OS doesn't have a clock, it just reads time/date from BIOS.
