[2014.5.22] [UBUNTU] Ubuntu and Windows system time out of sync issues

When installing Ubuntu+windows dual system, the Windows and Ubuntu system time is out of sync, which is due to the Windows system default reading hardware system time of the motherboard BIOS as the local time of the OS; The Linux class OS takes hardware system time such as the motherboard BIOS as UTC time (World standard Time, close to Greennwich time). Then the operating system's time is set in UTC according to the user's time zone setting Gaga minus. This has created a very interesting phenomenon for Chinese users: Ubuntu will be 8 hours faster than Windows (as for how to count the children's shoes to break their fingers; does it mean Ubuntu fast Windows?). ）。

The method of solving the problem, a kind of https://www.wikai.info/2011_01_477.html according to the method circulating on the network. Let Windows indulge Ubuntu, I do not like to change the list under Windows, always think this is very vainly disobey, tend to change in Ubuntu. I took a few hot stickers on the web and summed up my work in the context of my hardware and software:

1. Turn off UTC; Command used:

sudo gedit Etc/default/rcs

Note "RcS", s capital, and "Utc=yes" to "Utc=no" in the displayed content

2. The time is still to show the original "Fast" time, you can use the network time server to correct;

sudo ntpdate pool.ntp.org

Note that this tuning Linux server address is very demanding and must be Linux, and you have to turn on NTPD, time two service. Verify that very many servers are still work only to find this pool.ntp.org , please. Industry conscience. Of course. The conscientious will be able to add.

3. Be able to consider writing the corrected time to the hardware system, command

HW Clock

4.It ' s done! Enjoy it.
