在systemd下管理Linux系统的时间和日期的方法是怎样的

Systemd is a system and service manager for Linux systems. It provides a standard way to manage the system time and date. The systemd-timedated service is responsible for managing the system time and date. This service can be configured using the timedatectl command.

The timedatectl command can be used to set the system time and date, and to view the current settings. The command can also be used to set the time zone.

To set the system time, use the following command:

timedatectl set-time "YYYY-MM-DD HH:MM:SS"

To set the system date, use the following command:

timedatectl set-time "YYYY-MM-DD"

To set the system time zone, use the following command:

timedatectl set-timezone "zone"

The timedatectl command can also be used to enable or disable the automatic adjustment of the system clock for daylight saving time. To enable the automatic adjustment, use the following command:

timedatectl set-ntp true

To disable the automatic adjustment, use the following command:

timedatectl set-ntp false
