Changing the timezone on a debian Linux

Configuring backups for my server I have seen it is configured in UTC timezone, to change it I used dpkg-reconfigure tzdata command:

>#dpkg-reconfigure tzdata
Current default timezone: 'Europe/Madrid'
Local time is now:      Sat Apr 30 15:35:13 CEST 2011.
Universal Time is now:  Sat Apr 30 13:35:13 UTC 2011.

then I could choose the timezone correct for my country.

command tzconfig is deprecated.
