统信UOS命令行更改时间

统信UOS命令行时间管理设置 timedatectl 查看系统时区

root@fanjichang-PC:/usr/share/fonts# timedatectl
               Local time: 六 2021-05-08 15:01:27 CST
           Universal time: 六 2021-05-08 07:01:27 UTC
                 RTC time: 六 2021-05-08 15:01:25
                Time zone: Asia/Shanghai (CST, +0800)
System clock synchronized: no
              NTP service: active
          RTC in local TZ: yes

Warning: The system is configured to read the RTC time in the local time zone.
         This mode cannot be fully supported. It will create various problems
         with time zone changes and daylight saving time adjustments. The RTC
         time is never updated, it relies on external facilities to maintain it.
         If at all possible, use RTC in UTC by calling
         'timedatectl set-local-rtc 0'.

timedatectl list-timezones 显示所有可用时区 sudo timedatectl set-ntp false 关闭网络同步时间服务 sudo timedatectl set-timezone America/New_York 设置系统时区

当需要手动更改系统本地时间时，需要先手动关闭网络同步时间服务。关闭网络同步时间服务后，以设置系统时间为2021年5月8日10：11：50为例，命令如下

sudo timedatectl set-time 2021-05-08 设置系统日期 sudo timedatectl set-time 10:11:50 设置系统时间
