Display absolute timestamps (in local time)

Question

Screenshot / Code Snippet

About

This script converts relative timestamps to absolute timestamps, displayed in your local time zone. For times less than one hour ago, I leave the "x mins ago" relative timestamp, because I think that is more useful in such short timeframes. In all cases, the tooltip is updated to an absolute, local timezone.
