<B><font color="#FFOOOO">DO NOT USE AS AKAMAI PARSED PAGES NEVER RETURN THE LAST MODIFIED DATE!  THEY RETURN THE CURRENT TIME ALWAYS!</font></B>

<b>What does it do?</b>
Outputs the last modified date of the document you are working on in the format of:
Monday, November 8th, 2004: Page updated at 10:46 AM 

<b>How do I use it?</b>
(place the JS file somewhere on the page and put the function call OutputLastModifiedDate where you want the date to show up)
&lt;script src="/js/standardFunctionality/STSpecific/OutputLastModifiedDate.js"&gt;&lt;/script&gt; 
&lt;script&gt;OutputLastModifiedDate();&lt;/script&gt;
