In linux, CST and EDT time conversion and system time and network time synchronization

In linux, CST and EDT time conversion and system time and network time synchronization require the same time for each node during the experiment, however, because the time of some nodes is EDT, the time of some nodes is in CST format. So to convert EDT to CS... in linux, CST and EDT time conversion and system time and network time synchronization require the same time for each node during the experiment, but because of the time of some nodes
It is the EDT time, and the time of some nodes is in CST format. The command to convert EDT to CST time is as follows: mv/etc/localtime. bakln-s/usr/share/zoneinfo/Asia/Shanghai/etc/locaktime use the preceding two commands to change the EDT time to the CST time. Synchronize system time and network time install ntpdate tool sudo apt-get install ntpdate set system time and network time synchronization ntpdate cn.pool.ntp.org write system time into hardware time hwclock -- systohc the above steps can be achieved synchronization of system time and network time
