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

Surely the same can be said of the following
1) 11:59pm is 1 minute before 12:00pm. 11:59pm is obviously just before
midnight, so 12:00pm is midnight.
2) 11:59am is 1 minute before 12:00am. 11:59am is obviously just before
noon, so 12:00am is noon.

Confusing aint it

When I get confused as to when 12:00pm and 12:00am occur, I use the
following trick to remind me.

1) 12:00pm is 1 minute before 12:01pm. 12:01pm is obviously just after
noon, so 12:00pm is noon.
2) 12:00am is 1 minute before 12:01am. 12:01am is obviously just after
midnight, so 12:00am is midnight.

But I'm with you, just 1 more reason to use a 24-hour clock. Oh wait,
isn't
that where the 00:00 and 24:00 confusion came in? <g>

Hallo Peter,

You are right; 12:00 AM is used for midnight. Apparently I'm
not the only one confused by this:
<http://en.wikipedia.org/wiki/12-hour_clock#Confusion_at_noon_
and_midnight>.
One more reason to stay with 24hr notation :-)

Joep,

If I run 12:00a through a test program, I get 24:00.

Here's the code:

d tijd s 10a inz('12:00a')
d c_p c 'P'
d c_pm c ' PM'
d c_am c ' AM'
d timupd s 6p 0 inz

/copy qrpglecpy,prattribs
/copy qrpglecpy,prqc2le
/free

Reset tijd;
If %subst(tijd:6:1) = c_p;
%subst(tijd:6) = c_pm;
Else;
%subst(tijd:6) = c_am;
EndIf;
timupd = atoi(%char(%time(tijd:*usa):*iso0));

*inlr = *on;
Return;

/end-free

When debugging, the field timupd is set to 240000.

So if I combine this with the date of 20000101, it seems to

point to

midnight between 1 and 2 January 2000.

When initializing the tijd field to '12:01a', I get (as expected) a
value of 000100 in the timupd field.

Very strange to understand, though.
