Set and modify centos System Time Zone

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

1. view the time and date

Date

2. Set the time and date

Set the centos system date to the June 10, 1996 command

Data-s 06/22/96

Set the centos system time to 01:52:00 P.M..

Date-s 13:52:00

3. Write the current time and date to the BIOS to prevent failure after restart

Hwclock-W

Iii. Scheduled synchronization time

#/Usr/sbin/ntpdate 210.72.145.44>/dev/null 2> & 1

In this way, we have completed the problem of setting and modifying the centos system time zone. I hope you can learn more.
