Can't be, because PM means "in the post meridiem half of the day", and 12
hours and 1 minute after noon is in the ante meridiem half of the next day.
Thus it works for those who do not understand zero.  The correct notation
is 00:01PM.  The 24 hour system uses that notation: one writes 00:30 for
thirty minutes past midnight, not 24:30.

And 12:00PM is midnight, because that is the twelfth hour in the post
meridiem half of the day.  Nonsensical, of course, but the whole system is
buggy.

7PM means the seventh hour in the post meridiem half of the day.  7AM means
the seventh hour in the ante meridiem half of the day.  12:00 means either
midnight or noon, both of which are boundaries.  Digital clocks should
never display 12:xx unless the are 24 clocks, in which case they should
never display 24:xx.
