Many a times after initial installation of Linux operating system we see the date not to be in our local timezone, instead its in default PST time zone, So here are the steps which will guide you to have your local time zone. So lets start the action
The system dates are displayed using a reference from a file in you /etc directory called localtime, if you change this your r almost done,….
ashwin-server:/opt/# ll -a /etc/localtime -rw-r--r-- 1 root root 265 2011-02-07 14:47 /etc/localtime
But the real struggle is you wont be able to change the file or edit it because it is timezone data format, By default linux distribution has predefined almost all timezone data files prebuilt, so now its only matter of copy and paste. All the timezone data files are located in the “/usr/share/zoneinfo/” directory. Just Select the correct zone from the directory and your are almost done only 3 more steps remaining.
Check the current date we would be changing our timezone to Indian Standard Time Zone from Eastern Standard Time Zone
ashwin-server:/opt/# date Mon Feb 7 04:14:10 EST 2011
First rename the Original file to different name
ashwin-server:/opt/# mv /etc/localtime /etc/localtime.old
Either copy your localzone data file or create a Symbolic link to the /etc directory
ashwin-server:/opt/# cp /usr/share/zoneinfo/Asia/Calcutta /etc/localtime
OR
ashwin-server:/opt/# ln -a /usr/share/zoneinfo/Asia/Calcutta /etc/localtime
And hurray Check your System time again
ashwin-server:/opt/# date Mon Feb 7 14:47:26 IST 2011
Thanks.
