Option to display absolute dates and times instead of relative, e.g. "25 days ago"

All dates in the web interface are displayed relative to today. It would be nice if there was an option to show the exact dates and times instead, or an option to automatically display dates if the timestamp is a set amount of time ago. Something like '2 hours ago' is useful, but 'about a month ago' is already a lot less useful (to me).
