How to permanently change the time in Ubuntu Server

Question

I have changed the time in Ubuntu Server 11.04 but when i reboot it resets to the default it has. How to change the time that when I boot it stays like i changed it. already tried date but I think this is only temporary.

Solution 1

Sounds like you have a timezone issue. The easiest way to fix this is to reconfigure the tzdata package sudo dpkg-reconfigure tzdata

There are alternative ways, like symlinking the correct zonefile from /usr/share/zoneinfo to /etc/localtime which will inform the system of the proper time:

ln -sf /usr/share/zoneinfo/America/New_York /etc/localtime

However, it's preferred to use dpkg-reconfigure

Solution 2

If your timezone is set up correctly, I think you have to adjust your hardware clock with the command hwclock.

date is permanent if you are not using a timeserver and the correct timezone ;)

@Marco - Thank you the problem was in the timezone. I did 'sudo dpkg-reconfigure tzdata', selected the correct place and done. Works perfect after reboot. If you can put it as an answer i will voted up.
