Here is datetimectl output, Why local time is not set to Universal time? And I have enable ntpd service. The local time should be Sun 2013-08-11 21:45:21 UTC.

     Local time:  Mon 2013-08-12 05:45:21 CST
  Universal time: Sun 2013-08-11 21:45:21 UTC
        RTC time: Sun 2013-08-11 21:45:21
        Timezone: Asia/Shanghai (CST, +0800)
     NTP enabled: yes
NTP synchronized: yes
 RTC in local TZ: no
      DST active: n/a

By the way , My pc is equiped with dual System(archlinux/win7).

It's hard to know what's wrong without knowing when those time stamps were taken. Can you provide what you expect local time to be? – user606723 Aug 11 '13 at 14:05
Everything seems ok: UTC Sunday 21h -> Local time (+8h) Monday 5h. What local time do you expect? – Nicolas Aug 11 '13 at 20:23
The UTC time is the right time in my time zone. – jilen Aug 12 '13 at 11:08
@Nicolas Do you mean the UTC time is not correctly? It should be 8 hours before? – jilen Aug 12 '13 at 11:12
@jilen I don't know if your UTC time is good or not (just compare on internet to be sure). I just want to say, as you choose the Asia/Shangai timezone your localtime will be equal to the UTC time +8H – Nicolas Aug 12 '13 at 11:18

This problem might be related to this. You need to setup your bios.

Now, I erase the entire disk, and time is correctly. – jilen Aug 18 '13 at 16:50

First of all you have to be sure of your TimeZone. If it's well Asia/Shanghai, you will have a different of +8 hours between the UTC and your local time.
It's normal, UTC time means universal time: the same for everyone. Although local time is the time of your country/city and it depends where you live.
So, only the people who live near the Greenwich meridian (+0H) have the same UTC and local time.
In my understanding, your time system works well. You misunderstood what UTC and local time are.
