修改系统时间 分为System Clock（系统时间）和Real Time Clock （硬件时间，简称RTC）
使用root用户查看系统时间 #date
查看硬件时间# hwclock --show
更新系统年月日# timedatectl set-time 2017-06-13
更新系统时分秒# timedatectl set-time 10:25:17
将硬件时钟调整为与系统时钟一致 timedatectl set-local-rtc 1
或者# hwclock --systohc --localtime
将日期写入CMOS clock –w
修改时区：（将Asia/shanghai-上海时区写入当前时区）#cp -f /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
