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
I. Time Zone
1. view the current time zone
Date-R
2. Modify the time zone
Method (1)
Tzselect
Method (2) Limited to RedHat Linux and centos Systems
Timeconfig
Method (3) applicable to Debian
Dpkg-reconfigure tzdata
3. Copy the corresponding time zone file, replace the centos System Time Zone file, or create a link file.
CP/usr/share/zoneinfo/$ main Time Zone/$ Time Zone/etc/localtime
Available in China:
CP/usr/share/zoneinfo/Asia/Shanghai/etc/localtime
Ii. Time
Centos synchronization time and change Time Zone
