(转)同步时间

首先设置一下时区，然后打开ntp同步服务

timedatectl list-timezones
timedatectl set-timezone Asia/Shanghai
timedatectl set-ntp true

硬件时间问题

查看硬件时间总是报错，怕不是硬件问题吧

[tanglizi@archlinux ~]$ hwclock 
hwclock: Cannot access the Hardware Clock via any known method.
hwclock: Use the --debug option to see the details of our search for an access method.

[tanglizi@archlinux ~]$ hwclock --debug

No usable clock interface found.
hwclock: Cannot access the Hardware Clock via any known method.

好吧问题解决了，详见 这里只需要使用root权限就好（hwclock为啥不报权限不足啊，满满的误导 ``` sudo hwclock -w ```
