二、系统时间管理与控制

    使用timedatectl命令管理时间:
 [root@linuxidc log]# timedatectl 
      Local time: Thu 2015-01-08 11:31:31 CST
  Universal time: Thu 2015-01-08 03:31:31 UTC
        RTC time: Thu 2015-01-08 11:31:32
        Timezone: Asia/Chongqing (CST, +0800)
    NTP enabled: yes
NTP synchronized: no
 RTC in local TZ: no
      DST active: n/a

    timedatectl常用命令：
 [root@linuxidc log]# timedatectl --help
  status                Show current time settings
  set-time TIME          Set system time
  set-timezone ZONE      Set system timezone
  list-timezones        Show known timezones
  set-local-rtc BOOL    Control whether RTC is in local time
  set-ntp BOOL          Control whether NTP is enabled
