The Most Accurate Watch Face

Usually, when you look at your watch, the information you see is already a nanosecond or two out of date by the time the light reaches your eyes (depending on how far away you hold your watch), to say nothing of the delays introduced by your neural processing. Not so with this watch face, which *always* displays an answer to "what time is it?" that is accurate down to the tiniest fraction of a zeptosecond. Tap the center to flash the current time for a few seconds, so it isn't totally useless.
