Ubuntu + Windows Dual system time is not a solution

It's been a while since I last wrote a blog.

Because of the usual use of Linux and Windows, so installed a dual system

But finding a more tangled problem is that time is always wrong.

After finding the answer on the Internet, I realized that the system time and the correct time is just 8 hours.

What is the reason for that?

Summary of the online conclusions are:

The reason is that the default time between Ubuntu and Windows is managed differently

The Ubuntu default time is to take the BIOS time as gtm+0 time, while our country is in the East 8 area namely Gtm+8

That way, the time will be accurate when only one of the Ubuntu systems is installed.

Windows default time to take the BIOS time as local time, of course windows can network synchronization time

It also changes the BIOS time at sync time, so when you go into the Ubuntu system again, time will turn into normal time + 8 hours.

Enabling Windows after Ubuntu sync time can lead to a normal time-8 hours

The solution to this problem is to have windows and Ubuntu time management the same way

Either one can be changed

You will generally choose to change Ubuntu bar

The Change method is:

sudo gedit/etc/default/rcs
changed utc=yes to Utc=no.

Reboot the problem to find the perfect solution.
