Given that "a.m." is "ante meridian" and "p.m.", "post meridian", then
properly speaking neither 12:00 noon (at the meridian) nor 12:00 midnight
(opposite the meridian) is either a.m. or p.m., is it?
Of course, I'm saying this without consulting what the spec says. In this
fallen world, I'm sure one or the other was assigned a.m., the other, p.m.,
just to keep the standard simpler and more confusing. 12:00 midnight would
belong to neither day, but inasmuch as it is considered 12:00am, I think
that should make it the first minute of the day not the last, right? (If
it's the last, then 720 minutes of p.m. are followed by one minute of a.m.
before the day changes at 12:01 to get another 719 minutes of a.m.)

Now, really to split the difference between a decimal standard and one that
favors even divisions by twos, threes and fours, we should switch
everything to base-12 numbering systems shouldn't we?
To make this a post about XSL, maybe we should contemplate doing this and
getting rid of the mod operator while we're at it. (Who needs grouping anyway?)
