在新版的ubuntu中，使用timedatectl 替换了ntpdate来进行时间管理。ubuntu
1.查看当前时间状态ui
查看当前时间状态 timedatectl status ：code
wxs@ubuntu:~/6-1/task4$ timedatectl status Local time: Tue 2017-11-07 18:14:30 PST Universal time: Wed 2017-11-08 02:14:30 UTC RTC time: Wed 2017-11-08 02:14:29 Time zone: America/Los_Angeles (PST, -0800) Network time on: yesNTP synchronized: yes RTC in local TZ: noio
系统显示的时间是错误的，错误缘由也是显而易见的，使用的是America/Los_Angeles的时区。class
所以只要修改时区就能保证时间的正确。require
2.修改时区date
全部的时区名称存储在/usr/share/zoneinfo文件中。rsa
执行命令timedatectl set-timezone "Asia/Shanghai" 就能够将时区设为上海时区。im

从新查看当前时间状态 timedatectl status ：
wxs@ubuntu:~/6-1/task4$ timedatectl status Local time: Wed 2017-11-08 10:15:45 CST Universal time: Wed 2017-11-08 02:15:45 UTC RTC time: Wed 2017-11-08 02:15:45 Time zone: Asia/Shanghai (CST, +0800) Network time on: yesNTP synchronized: yes RTC in local TZ: no
