I'd go for the microformats way of representing time, now that they've standardized it: http://microformats.org/wiki/datetime-design-pattern http://microformats.org/wiki/datetime-design-pattern <abbr class="foo" title="YYYY-MM-DDTHH:MM:SS+ZZ:ZZ">Date Time</abbr> There are a lot of good alternatives proposed and debated on that page, so I'm confident that they've come up with the best way to represent the date in the DOM. Additionally, it's readable from Javascript-less environments and and uses only standard elements and attributes.
