    Re: 0000 not 2400?

     A.M. and P.M. are abbreviations for ?ante meridiem? and ?post meridiem?.  They
    mean ?before noon? and ?after noon? respectively.  Noon is neither before or
    after noon; it is simply noon.  Neither A.M. or P.M. are therefore correct.
    Midnight is both 12 hours before noon and 12 hours after noon.  Therefore,
    either 12 A.M. or 12 P.M. could work as a designation for midnight, but both are
    ambiguous.  (From NIST, ISO member).
