ubuntu 22.04版本修改时区的操作方法
修改时区比较简单,就是timedatectl set-timezone America/Los_Angeles加systemctl restart systemd-timesyncd,并且服务器重启后时区没有变回去还是修改后的
示例:
目前时区是UTC 0时区伦敦时间,想改成太平洋时区(Pacific Time,PT)的洛杉矶时间,PDT是指太平洋夏季时间(Pacific Daylight Time),PST是指太平洋标准时间(Pacific Standard Time)。太平洋夏季时间从每年3月的第二个星期日到11月的第一个星期日期间和北京时间差15小时,其余月份和北京时间差16小时。太平洋夏季时间时制结束后就是太平洋标准时间(Pacific Standard Time)。
