Ok, yes that sounds reasonable.
I guess in the meantime instead of getting a time at midnight I should
opt for another, say 11pm? I think I saw another post somewhere that
recommends doing this to combat daylight savings time problems.
And I'll wait and see whether it is something that can be addressed by
PHP or whether as you say it is an OS issue.

OK! That actually seems reasonable. In Europe at least, the DST
time-change is defined to take place at 01:00:00, so the hour from
01:00:00 to 01:59:59 does not exist on that date.
So it look like the bug is that the times for the hour between 00:00:00
and 00:59:59 are wrong on a date when the clock goes back for DST.
Now that we have this pinned down, I'm going to kick this to a
developer who knows about the relevant bits of the PHP source to say
whether this is something PHP can address, or whether it's a bug in the
date/time handling of MacOS X that you'll just have to live with.

The first result I get is when mktime() is set to:
$the_day=mktime(2,0,0,3,30,2003);
and the result is:
1048989600
instead of -1

Maybe -- or maybe my arithmetic is off!
Could you possibly do a bit more testing and report the first time
after 01:01:03 that you get a likely result (and what it is!)?

really screwy then :-)
With the script:
<?PHP
$the_day=mktime(0,0,0,3,30,2003);
echo "$the_day<br>";
echo "23:59:59 29-Mar = ", mktime(23, 59, 59, 3, 29, 2003), ";
01:01:03 30-Mar = ", mktime(1, 1, 3, 3, 30, 2003);
?>
I get the result:
-3662
23:59:59 29-Mar = 1048982399; 01:01:03 30-Mar = -1

H'mmm -- I get
23:59:59 29-Mar = 1048982399; 01:00:01 30-Mar = 1048982401
on my system, which is what I expected from your report. There seems
to be an extra minute or so of limbo on yours for some reason. Can you
try again with:
mktime(1, 1, 3, 3, 30, 2003)
and let us know the result. If it's about 1048982463, then it seems
there's a whole minute in there for which you don't seem to be able to
get a valid time. If it's anything else, then something is really
screwy. Either way, it seems to be a real bug.
