? Using XHTML? XHTML is a content description language, and has no imperatives, nor facilities for data conversion.
object for the conversion:
var date = new Date(1000 * epoch);
var text = date.toString();
If you encapsulate the epoch times in the XHTML content using for example a <span class="datemagic">epoch</span>
Actually, it might be pretty nifty in any case: the page could display the times in local time, without any intervention from the server.
1327486488 seconds since epoch is "Wed Jan 25 10:14:48 2012 UTC", but I have no idea what the 676088 refers to, or how it affects the date.
