Chris Schmidt wrote it actually, so I can't claim the credit for it.

I think I was the first person to suggest that ;-)

Mostly because nobody has written code to do it.

What T would that be? I assume you're seeing dates in raw ISO format
but I'm certainly not. When I look at a history page like:

  http://www.openstreetmap.org/browse/way/20169321/history

the dates look like:

  Fri Aug 08 10:37:58 +0100 2008

Again, it is in my browser...

That limit is nothing to do with the server, it's to do with the
browser - most browsers can't cope with large numbers. Firefox 3 does
seem to manage rather more though I agree.
