Solution
The time zone can be changed by following the steps below: 1) First locate the desired timezone from the available time zone /usr/share/zoneinfo. In this example, we are trying to change the timezone of the compute node to IST. [root@elorl03cn01 zoneinfo]# cd /usr/share/zoneinfo
[root@elorl03cn01 zoneinfo]# ls Africa Asia Canada Cuba EST Factory GMT0 Hongkong Iran Japan Mexico Navajo Poland PRC ROK Universal W-SU America Atlantic CET EET EST5EDT GB GMT-0 HST iso3166.tab Kwajalein Mideast NZ Portugal PST8PDT Singapore US zone.tab Antarctica Australia Chile Egypt Etc GB-Eire GMT+0 Iceland Israel Libya MST NZ-CHAT posix right Turkey UTC Zulu Arctic Brazil CST6CDT Eire Europe GMT Greenwich Indian Jamaica MET MST7MDT Pacific posixrules ROC UCT WET So we have to select Calcutta under Asia directory /usr/share/zoneinfo/Asia
[root@elorl03cn01 Asia]# ls -lrt Calcutta -rw-r--r-- 2 root root 265 Aug 9 2010 Calcutta [root@elorl03cn01 Asia]# pwd /usr/share/zoneinfo/Asia 2) Take the back up of the existing configured timezone mv /etc/localtime /etc/localtime.bakup
3) Then copy the desired time zone to localtime. cp /usr/share/zoneinfo/Asia/Calcutta /etc/localtime
4) Then re-start the ntpd service [root@elorl03cn01 Asia]# /etc/init.d/ntpd status
ntpd (pid 29365) is running... [root@elorl03cn01 etc]# /etc/init.d/ntpd restart Shutting down ntpd: [ OK ] Starting ntpd: [ OK ] 5) Verify the timezone; it should have been changed to IST [root@elorl03cn01 Asia]# date
