How To Sync Time Between Linux And Windows Dual Boot. Dual Booting has become very common among people trying out different Linux Distributions while still keeping their windows system. This has become extremely popular since it is so easy to do. However, one big problem with dual booting is the Time.
Yes, you read that right. When you are using only one Operating System your system sync time effortlessly. But when on a dual boot of Windows & Linux, there can be a time sync error. Linux uses GMT while Windows uses your Local time. When you log in to Windows after spending time with Linux or vice versa, there might be incorrect time displayed. Worry not, as we have a simple solution for this.
Just click on the start menu in your windows system and search for regedit.

New >> DWORD(32 bit) Value.
After you have done that, the new entry you created will be highlighted by default. Rename it to
RealTimeIsUniversal and give it a value of 1.
We are done with all configurations and next time you reboot, you will not have the time sync problem.
