Universal-Time-Fix-for-Dual-Boot-Linux-and-Windows

Noob people like me or others face some critical problem while using dual boot with Linux and Windows. One of the main problem is the universal time fixing.

While using dual boot, usually clock time gets reset once we change boot from linux to windows. This occurs mainly for bios clock reset for dual boot start. we can solve this problem easily by following any of the following steps.

1. Windows solution
2. Linux solution

It is better to follow the windows solution for this.

Windows Solution:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]
"RealTimeIsUniversal"=dword:00000001

• Next, save that file as WindowsTimeFix.reg and exit Notepad. Then, navigate with your file browser to the directory where you saved the file we just saved, and double click it. A box will pop up essentially asking if you want to proceed, tell it that you do.

• Once that is done, you'll also want to disable Windows syncing the time. To do this, you'll want to go to your services application by clicking your start menu and typing services.msc, and clicking Services. Once there, scroll down until you find Windows Time and right click it, selecting Properties. From here, stop the process, and disable it as well.

• Or, run the following command in cmd

sc config w32time start= disabled 

Run the command from an elevated command prompt instead(run cmd as administrator).

• To turn the Windows Time service back on at a later point in time, run the command

sc config w32time start= auto

• Once Windows Time has been stopped and disabled and the registry key has been changed, your Windows will no longer have the time issue whenever you switch back and forth between GNU/Linux.

Linux Solution:

The solution, or rather, multiple possible solutions, are all quite easily solved. My preferred method for this issue is to make the GNU/Linux system use localtime instead of UTC. To do this on any modern system using SystemD, use the following command:

sudo timedatectl set-local-rtc 1

And done. That was easy!
