One of Vista's unadvertised, and probably underappreciated, features is the ability to stop time:
It's actually quite disconcerting, because I glance at the time alot, but it doesn't really consciously register with me what time it is. After about 30 minutes, I start thinking that it seems like time is dragging on. Then I'll notice the discrepancy with the IRC timestamp, and the world becomes clear again (and hopefully I'm not late for anything).
I'm sure stopping time will come in handy next time I have a deadline to meet.
