CentOS modify system time zone

After the newly installed centOS system, there may be a time zone difference of 8 hours from the existing normal time due to time zone issues. We can reset the time zone through the corresponding command.

[root@master ~]# timedatectl
               Local time: Mon 2021-01-25 07:03:18 UTC
           Universal time: Mon 2021-01-25 07:03:18 UTC
                 RTC time: Mon 2021-01-25 07:03:32
                Time zone: UTC (UTC, +0000)
System clock synchronized: no
              NTP service: active
          RTC in local TZ: no

1. View various statuses of time:

[root@master ~]# timedatectl
      Local time: Mon 2021-01-25 14:57:51 CST
  Universal time: Mon 2021-01-25 06:57:51 UTC
        RTC time: Mon 2021-01-25 06:57:51

2. List all time zones:

timedatectl list-timezones

3. Adjust the hardware clock to be consistent with the local clock, 0 is set to UTC time:

timedatectl set-local-rtc 1

4. Set the system time zone to Shanghai:

timedatectl set-timezone Asia/Shanghai
