BBC News (UK) has a countdown timer in its opener, for example see this video.
On the bottom right, there's a countdown timer which counts the time until the news begin. But I find the timer somehow weird because it seems to count seconds and some unit I can't figure out. At the beginning, I thought it would be every tenth millisecond but that would mean that it would have to count down from
XX being the seconds). But at some point I noticed that the highest number seems to be about
XX:24. At least for the 2008 theme, Wikipedia mentions the countdown would indeed count down "every 10 milliseconds" but that can't be true for 2013 anymore :-).
