RE: Timestamp edit code problem with midnight as00:00:00butIwant 24:00:00

Then how would you compare these two figures, as they point to exactly
the same moment (that instance where the secondhand reaches the twelve,
so right after 23:59:59.99999999?)? Is 00:00:00 smaller than 24:00:00,
are they equal and if so how could that be? Human agreements are not
applicable here, we are dealing with computer 'science' here.

I can only agree with you that ISO8601 is a good agreement between two
human beings, however the computer has no idea whether the moment after
23:59:59.999999... is used as a referral to the end of the day, or the
beginning of the next day. In this case IBM has made the decision that
we all refer to that moment as 00:00:00 and not 24:00:00.

Kind regards,

Cor

Hi Cor

<snip>
There is no such time as 24:00:00, 24:00:00 only exists as
*HIVAL for time-fields if I'm not mistaken. This is purely a
matter of convention.
</snip>

According to ISO 8601 "time" represents the amount of time
that has passed in the day and that 24:00:00 should be used
when referring to the day's end and 00:00:00 should be used
when referring to the day's beginning.

For example: 2007-05-21 24:00:00 and 2007-05-22 00:00:00
refer to the same thing.

All the best

Jonathan
