//######################  putLastModified()  #######################
//
//	Formats and document.write()s the date and time obtained from the 
//	document.lastModified property.  Include this file where you want 
//	the date to appear and surround it with <SPAN></SPAN>, or something, 
//	to get the desired text effect.  For example:
//
//	<SPAN STYLE="font-size:8pt; color:#6699FF;">
//		<SCRIPT TYPE="text/javascript" LANGUAGE="JavaScript" SRC="Includes/putLastModified.js"></SCRIPT>
//	</SPAN>
//
//	Yields something like --  Last updated today (2005-03-16 19:03:02).
//
// 2005-03-16	Initial.
// 2005-04-27 Short circuit date formatting if we're pass something that 
//						doesn't parse into a date.
//
//	The original versions of lastMod() and takeYear() were taken from 
//	Peter-Paul Koch's CSS and JavaScript tips and tricks site 
//  http://www.quirksmode.org -- to quote Ray Bethel, "Good Stuff!"
