CentOS 7 resolves a 8-hour difference between local time and actual times

Through Date-s "2014-12-06 15:00:00" and timedatectl set-time "2014-12-06 15:00:00", as well as NTP and other methods are temporarily effective, distressed me half a day. Talk less, straight to the subject.

Step 1: Check the time to discover that local times is not correct, and universal is right. Then set the local time to: UTC (World Standard Time) No, it's OK.

[[email protected] ~] $ timedatectl
       Local time: Sat 2014-12-06 22:59:33 CST # 8 more hours live
   Universal time: Sat 2014-12-06 14:59:33 UTC
         Timezone: Asia / Shanghai (CST, +0800)
      NTP enabled: yes
NTP synchronized: no
  RTC in local TZ: no
       DST active: n / a

Step 2: View system time zone information

[[email protected] ~]$ ls /usr/share/zoneinfo/ Africa      Chile    GB         Indian       MST         PRC        UTC
America     CST6CDT  GB-Eire    Iran         MST7MDT     PST8PDT    WET
Antarctica  Cuba     GMT        iso3166.tab  Navajo      right      W-SU
Arctic      EET      GMT0       Israel       NZ          ROC        zone.tab
Asia        Egypt    GMT-0 Jamaica      NZ-CHAT     ROK        Zulu
Atlantic    Eire     GMT+0 Japan        Pacific     Singapore
Australia   EST      Greenwich  Kwajalein    Poland      Turkey
Brazil      EST5EDT  Hongkong   Libya        Portugal    UCT
Canada      Etc      HST        MET          posix Universal CET         Europe   Iceland    Mexico       posixrules  US
[[email protected] ~]$ 

Step 3: Delete the current system's time zone:

 
[[email protected] ~]$ sudo rm /etc/localtime 

Step 4: Create a soft connection from/usr/share/zoneinfo/to replace the current time zone information and select Universal directly:

 
[[email protected] ~]$ sudo ln -s /usr/share/zoneinfo/Universal /etc/localtime
[[email protected] ~]$ 

Step 5: Use timedatectl to view, OK problem solved.

[[email protected] ~]$ sudo timedatectl 
      Local time: Sat 2014-12-06 15:10:39 UTC
  Universal time: Sat 2014-12-06 15:10:39 UTC
        RTC time: Sat 2014-12-06 07:11:04 Timezone: Universal (UTC, +0000)
     NTP enabled: yes
NTP synchronized: no
 RTC in local TZ: no
      DST active: n/a

Note: CentOS linux:setting timezone and synchronizing time with NTP
