1I think you probably want superuser.– EdCNov 18, 2012 at 5:03

That isn't "time format", that is your timezone. And you can set the timezone used via the TZ environment variable (no root required, affects just you).– vonbrandJan 23, 2013 at 19:26

cp /usr/share/zoneinfo/Asia/Calcutta /etc/localtime
or
cp /usr/share/zoneinfo/Asia/Colombo /etc/localtime
Some distribution provide utilities for that like dpkg-reconfigure tzdata, tzselect, etc.
It's better to use
ln -s /usr/share/zoneinfo/Asia/Calcutta /etc/localtime
Because if you use cp and there is some change in the tzdata package you will need to make cp again.

Actually almost all linux distributions nowadays use a copy instead of a symlink. The main reason is, that you have the right timestamps also of early actions that happen before /usr is mounted. This might change again in the future when /usr wont be on a separate partition because udev/systemd/etc. wont support it anymore... Nov 21, 2012 at 0:48

Yes, i am agree with you, for /usr on a separate partition it's preferably to use a copy.– arutemusNov 21, 2012 at 16:18
This will help you to change the data time format to UTC+5:30 cp /usr/share/zoneinfo/Asia/Calcutta /etc/localtime or create a softlink.
