Re: Timestamp edit code problem with midnight as 00:00:00 but I want 24:00:00

In discussions here it was said that 00:00:00 and 24:00:00 are exactly the same point in time; that is, midnight, However the next comment was that they are not really the same because if you had asked Betty Boop to meet you today at 24:00:00 she'd be waiting for you tonight at midnight, not last night at midnight. Which raised the next question: What does the military do? Do they have such a time as twenty four hundred hours? Is zero hour really midnight?

What we have is a nomenclature that doesn't perfectly match our every day experience. I can't find the original discussion here, but I believe the current compiler behaviour is based on a standard, maybe ISO 8601? The behaviour is this:

23.59.59 + 1 second = 00.00.00
00.00.00 - 1 second = 23.59.59
24.00.00 + 1 second = 00.00.00

Note that you cannot increment your way to either 24.00.00 but you _can_ increment your way to 00.00.00. If I remember, the standard says that the day runs from 00.00.00 to 23.59.59, but for some obscure compatibility reason, 24.00.00 can be specified as a synonym for 00.00.00 in some cases.

I'm reasonably sure that Barbara or Simon had an excellent discussion on the topic, and I'm ashamed that I can't locate it.
