CentOS 7解决Local Time与实际时间相差8小时问题

通过date -s “2014-12-06 15:00:00”以及timedatectl set-time “2014-12-06 15:00:00” ,以及ntp等方式均知识临时有效，苦恼了我半天。废话少说，直奔主题。

Step 1：查看时间发现Local time不对，而Universal time是正确的。那么将本地时间设置为：UTC（世界标准时间）不就行了嘛。

[mdrill01@mdrill03 ~]$ timedatectl 
      Local time: Sat 2014-12-06 22:59:33 CST　　　　#活生生的多了8个小时
  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
[mdrill01@mdrill03 ~]$ 

Step 2：查看系统时区信息

[mdrill01@mdrill03 ~]$ 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
[mdrill01@mdrill03 ~]$ 

Step 3：删除当前系统所处时区：

[mdrill01@mdrill03 ~]$ sudo rm /etc/localtime 

Step 4：从/usr/share/zoneinfo/中创建软连接以替换当前的时区信息，直接选择Universal：

[mdrill01@mdrill03 ~]$ sudo ln -s /usr/share/zoneinfo/Universal /etc/localtime
[mdrill01@mdrill03 ~]$ 

Step 5：利用timedatectl查看，OK问题解决。

[mdrill01@mdrill03 ~]$ 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
