http://www.dynamicdrive.com/forums/archive/index.php/t-20242.html

But i want on this script if time is up stop the script and try another countdown for 3 hours and show the countdown like this (XXhours : XXminutes : XX seconds left until the end of happy hour !).
Once the happy hour is finish, the script restart.

In brief I want 2 countdowns interlocked.
