Only once, ever

How many events happen only once in history? One of our IT people at work pointed out that last Wednesday morning, at two minutes and three seconds after 1 o'clock, the time and date was 01:02:03:04:05:06.

Well, but wait a minute. Sure, that'll only happen once, ever; but so will this:
02:02:03:04:05:06.

And this:
03:02:03:04:05:06.

And, anyway, what kind of a bizarre way is that to write the date and time? What about 01/02/03 04:05:06? Or 5/6/78 9:10? So is it just arbitrary that the first sequence seems so cool? An accident of integers and conventions for writing dates? Or is the first sequence more "natural" because each segment represents a progressively larger unit of measurement?

And can't I find anything more substantial with which to occupy myself on my day off?

leave it to the math guy to comment on this one.

the "successively larger units of measurement" theory is a nice one, but i don't think it's actually true.

the 01:02:03, 04/05/06 sequence is hr:min:sec, m/d/y. progressively larger would be sec:min:hr, d/m/y, in which case 01:02:03, 04/05/06 would be two minutes and one second after 3 o'clock on may 4th of this year.

the european date standard sequence is increasing units of measure.

since pi day (which just passed) is considered by date first (3/14), then time (1:59:26), maybe this sequence is only cool on 01/02/03, at 04:05:06, which was jan. 2nd of 2003. so you can tell your IT person "never mind, go home...show's over".
