Adaptive formatting for countdowntimer?

Nice job on this module! It seems to have everything I want: lots of formatting options, fairly easy to use (provided you're allowed to use full HTML). Now if it could just start the coffee maker when it times out...

Seriously, now that it works well, I'd like to suggest some way to do adaptive formatting.

This would adjust the output format to increase the resolution as the end time approached; something like: Show nothing finer than days until there's 2 days left; then include hours. For the last two hours, include minutes, then for the last two minutes include seconds. Drop off high-order items that have run to zero. Thus:

14 days
2 days
1 day 21 hours
6 hours
1 hour 12 minutes
58 minutes
1 minute 20 seconds
45 seconds

Thoughts?
