This is a very simple and basic script that allows to place countdown clocks on your web site. Unlike that one, whose computed time period depends on the settings of the visitor's computer, this script counts down to the server's date. It is very similar to countdown-clock.js, with the addition of a time differential factor: I use a mixture of JavaScript and PHP to find out the difference between the server and client dates, then I use that to synchronise things.
