Comments need timestamps

Hi folks!

I was just revisiting a thread and wanted to post a follow-up to one of Thor's comments. Before doing so, however, I wanted to be sure that his comment was indeed a month old (which it seemed to be, assuming he commented right after my original posting), and not badger him if the comment had just been added in the past few days.

Unfortunately, since comments are second-class objects and don't sport timestamps of their own, there was no way for me to know. So I just assumed my memory was serving me well today and that his comment was not recent and followed up with my query.

Please can you add timestamps to comments — there's just too much to hold in one's head already.

Thanks!

Rael
