2. Unless you need to for some reason I don't see here, don't mess
around with date & time.
What I'm trying to do is find a way to express "more than 60 minutes
after the most recent time/date stamp" in such a way that it will not
fail across noon/midnight boundaries. In Delphi, all times are just
expressed as floating point numbers, where each day is "1", 12 hours
is "0.5", etc, so all of these calculations are dead triviall in that
situation.
About as trivial as they are in Rev - use all your times in seconds and
it's just as easy (or easier - integers instead of floating point
numbers). If you want to convert them to human-readable date/time you
can - that's what convert does for you. But if you just need to
compare times, then I find it easier to stick to seconds.
Ah. More puns. So "the seconds" means something different than
"seconds". I guess "the seconds" is what I was looking for all
along. Difficult to spot, since it is more or less a time/date
concept masquerading as a time. But, that said, this simplifies
things considerably.
In my own code, I would probably use "seconds()" rather than "the
seconds" - but it's personal preference; as a classical language
programmer, I find the function style more readable.
