RE: 00:00:00 or 24:00:00

If memory serves me right, the use of 24:00:00, to refer to the end of the
day, is to accomodate previous (and long standing) standards used by the
military. As such ISO 8601 indicates:

<quote>
day, calendar
time-interval starting at [0000] and ending at [2400] (which is equal to
the beginning of the next calendar day);
typically a calendar day has a duration of 24 h

It is confusing to have two accepted ways to represent the same point in
time and I do recall that this has always been a sore point with the
chief database architect back in Rochester -- but a point that he (and
us) have to live with...
