According to the recommendation on Arch Wiki, I set my hardware clock to UTC. And here is the result of timedatectl status on my machine when just booted:

      Local time: Tue 2013-07-02 15:38:03 CST
  Universal time: Tue 2013-07-02 07:38:03 UTC
        Timezone: Asia/Shanghai (CST, +0800)
     NTP enabled: yes
NTP synchronized: no
 RTC in local TZ: no
      DST active: n/a

At this moment, the time display on panel is UTC, only after a while(about 10 minutes), the NTP synchronized will eventually change to yes, then I have CST on the panel. So how can I force the NTP sync as soon as booting?

@slm, it doesn't work, I tried to manually start the daemon after booting, nothing happened, it seems I still have to wait. – Elderry Jul 2 '13 at 8:48

Add iburst to the server line in ntp.conf. Your ntp.conf will have one or more lines that look like:


Add iburst to the end of each line. After the change they should looke like:

server iburst
server iburst

then reset ntp
