====== Setup timezone and update time from NTP ======
Having correct time on a server is very important. For example, you cannot join a Windows PC to a Domain if the time differs more than a few minutes (Five minutes if I'm not mistaking).

To setup time zone and update time from internet on Ubuntu Server, do the following:

Check timezone
<code>
$ date
Thu Mar 21 18:02:49 MST 2012
</code>

or check timezone file

<code>
$ more /etc/timezone
Europe/Zagreb
</code>

Setup timezone
<code>
sudo dpkg-reconfigure tzdata
</code>
and follow the instructions

Also, be sure to restart cron as it will not be aware of the change otherwise
<code>
$ /etc/init.d/cron stop
$ /etc/init.d/cron start
</code>
You can also update your time periodically by creating a daily crontab (crude but it works)
<code>
$ vim /etc/cron.daily/ntp
</code>
With the contents
<code>
#!/bin/sh
ntpdate zg1.ntp.carnet.hr zg2.ntp.carnet.hr
</code>
and make sure to make it executable
<code>
$ chmod 755 /etc/cron.daily/ntp
</code>
