How to change Ubuntu Server timezone

Here is a link to fine post How to set the timezone on Ubuntu Server. Here I just briefly repeat main steps:

• Check you local timezone with command more

  /etc/timezone

• If timezone is incorrect the type command

  sudo dpkg-reconfigure tzdata

  and follow screen instructions.
• If necessary restart cron (if any cron jobs are scheduled)

  /etc/init.d/cron stop
  /etc/init.d/cron start
