Setting date on Linux through the command line
It has always been said the setting the date through the command line is tough. Well I found it very very simple.
By default date command displays the current system date and time.
To set the system date and time you can use the - -set option with the date string. Of course to do that you will need root access.
( - - set ( hyphen hyphen set) without spaces. some browsers combine the two hyphens)
ie. date - -set=’dd/mm/yyyy hh:mm:ss’
or
date - -set=’27/04/2009 20:10:05′
that should set your date 
[end]
