When we use the centos system, problems may occur frequently in the time zone, and sometimes errors may occur after the change. Next we will learn a way to change this situation. If you are not using centos, run the yum install NTP command.

Then: ntpdate us.pool.ntp.org.

Because the centos system is re-compiled with the source code of rhAS, many places are exactly the same.

The Time Zone of rhas5 exists as a file. The current time zone file is in/etc/localtime.

So where are files stored in other time zones?

Under/usr/share/zoneinfo

We use UTC + 8, Beijing, and Shanghai time.

# Cp-F/usr/share/zoneinfo/Asia/Shanghai/etc/localtime
# Reboot

After the restart, view the time in date, view the current time zone date-R, view/modify the Linux time zone and time
