how to fix time when dual booting Ubuntu and Windows

[labbe5]

If you are dual booting Ubuntu (or Ubuntu derivatives) and Windows, you need to fix time when booting from Windows.

I use a Dog-based OS on a Windows machine from time to time, and my friend complains that the time is screwed when i am finished with my Ubuntu session.

There is a fix for that :

For version older than 16.04 :
sudo sed -i 's/UTC=yes/UTC=no/' /etc/default/rcS
and reboot

For 16.04 and newer :
timedatectl set-local-rtc 1
