Has anyone ever opened up the "Date and Time properties" dialog (double-click on the time in the the lower right task bar thingy) in Windows XP and just watched the second hand? I swear that every fifth second or so it just pauses for an extra tenth or quarter of a second or so. The clock is staying correct in the long run, so that implies that all the other seconds are actually short by a small but significant percentage. So obviously if it's able to correct everything to come out right in the end it knows how long a second should take, so why not just make it the right length in the first place? I'm very confused.
