Script: CountDown Timer
Description: Counts down or up from a date (this is the non-XML version)
Author: Andrew Urquhart
Home: http://andrewu.co.uk/clj/countdown/
History:
20040117 0035UTC	v1		Andrew Urquhart		Created
20040119 1943UTC	v1.1	Andrew Urquhart		Made more accessible/easier to use
20040317 1548UTC	v1.2	Andrew Urquhart		Implemented a less intrusive error message
20040331 1408BST	v1.3	Andrew Urquhart		Attempts to add to the currently window.onload schedule, rather than overriding it
20050210 1558GMT	v1.4	Andrew Urquhart		Saves a short-cut to the each countdown Id element and re-uses that rather than continually calling getElementById - faster. Also reduced all nouns to short-versions to decrease size of script
20050216 0018GMT	v1.41	Andrew Urquhart		Added support for IE4
