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.
