Bug Type: Date/time related
Operating System: MacOS X 10.2
PHP Version: 4.3.0
New Comment:
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.

ok, I used 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), ";
01:00:01 30-Mar = ", mktime(1, 0, 1, 3, 30, 2003);
?>
and got:
-3662
23:59:59 29-Mar = 1048982399; 01:00:01 30-Mar = -61
I thought it might be a daylight savings time problem as well, hence I
thought the extra parameter I normally use would solve the problem, but
it didn't. i.e.
$the_day=mktime(0,0,0,3,30,2003,0);
