How To Fix Incorrect Windows Time In Linux Dual Boot

In this video I will show you how to fix out of sync time on Windows when dual booting with Linux. This is something that has bothered me for years and I wanted to share a solution to it. The reason why this happens is that Linux sets the real time clock, which is the hardware clock managed by your BIOS, in UTC. While Windows maintains its clock in local time. So there is a conflict between the to time standards.

Commands:
timedatectl
timedatectl set-local-rtc 1 --adjust-system-clock

Thank you so much. I've just recently upgraded from 22.04 LTS to 24.04 and noticed the time discrepancy every time I switched between OS's (I also run Windows 10 on the same PC): I thought my BIOS CMOS battery was dying which seemed odd since I had just put in a new one a few months back.
For whatever reason, I didn't experience the problem with Ubuntu 22.04LTS. It only started after I upgraded to 24.04, but your solution resolved the problem nonetheless. So thank you again.

Thankyou. I thought something was up with my motherboard but this did the trick. I am able to switch from Kubuntu to Windows 10 with no time issues. For me it is really important to have right time cause for development the http requests are validated somehow to not send request in the future or in past to bypass subscription plan I am guessing

Fun fact: The way you pronounce the first and last "U" in Ubuntu is also how you pronounce the second "U" in Ubuntu

[darkchronoss]

And "timedatectl set-local-rtc 0 --adjust-system-clock" to revert?
