Script: DHTML Easy Countdown (Development Version - not intended for production use due to uncompressed size)
Description: Counts down or up from a date (this is the non-XHTML version)
Author: Andrew Urquhart
Home: http://andrewu.co.uk/clj/countdown/
History:
20040117 0035UTC	v1		Andrew Urquhart		Created
20040119 1943UTC	v1.1	"					Made more accessible/easier to use
20040317 1548UTC	v1.2	"					Implemented a less intrusive error message
20040331 1408BST	v1.3	"					Attempts to append to the current onload schedule, rather than overriding it
20050210 1558GMT	v1.4	"					Saves a short-cut to 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	"					Added support for IE4
20051231 0210GMT	v1.5	"					Switched to custom date format and custom date parser for better internationalisation and cross-browser compatibility (should fix reports of recent bugs in Mac browsers)
20060101 1649GMT	v1.52	"					Made counter update 0.1s after the last whole second to ensure that the browser doesn't render the display at the exact moment the counter changes - otherwise can appear to miss a second out
20070414 2313BST	v1.53	"					Added 'typeof CD_T' check to CD_T() and test for CD_OBJS[id] in CD_D incase references don't exist when the timeout resolves
