Fix dual system time problem
fix a dual system bug : windows time not right everytime after using ubuntu.
run this in ubuntu
sudo timedatectl set-local-rtc 1 --adjust-system-clock
why having this problem
there a hardware called RTC in your computer:
if RTC time is 00:00 , and you are in UTC+8:00 time zone ,
windows think : ok ,RTC time is just right : now is 00:00
ubuntu think : RTC time is UTC+0:00 so i have to add 8 hours and now is 08:00
command make ubuntu think in windows way.
