二、修改时区

首先在linux下输入命令“ date ”查看当前时间：

date

删除当前时间 命令：

rm-rf /etc/localtime #删除当前默认时区

将当前时区修改为上海时区命令：

ln-s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime #修改默认时区为上海

输入“ date ”查看当前时间，设置完毕

三、修改时间

当前时间：

date

修改时间：

date-s"20140225 20:16:00"#yyyymmdd hh:mm:ss

查看当前系统时间：

date

设置系统时间：

date-s"时间"

查看硬件的时间：

hwclock --show

设置硬件时间：

hwclock --set--date="10/28/2020 10:15:15“

设置系统时间和硬件时间同步：

hwclock --hctosys

保存时间（一定要保存设置，否则下次重新启动时，设置会失效）：

clock -w
