New Comment:
This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.
Thank you for the report, and for helping us make our documentation
better.
"Some times are invalid if DST is on. If DST is enabled in e.g. 2:00,
all times between 2:00 and 3:00 are invalid and mktime returns
undefined (usually negative) value. Some systems (e.g. Solaris 8)
enable DST in midnight so time 0:30 of the day when DST is enabled is
evaluated as 23:30 of the previous day."

I am running windows2k, php4.3.4, apache 2.0.48 and I encounter the
same issue with this code.
<?
print mktime(23,0,0,3,27,2004)."\n";
print mktime(0,0,0,3,28,2004)."\n";
?>
Outputs:
1080428400

I have the same problem running on Mac OS X
php -q -r 'print mktime(0,0,0,3,30,2003) . "\n";'

Same happens for 3/31/2003 so is clearly related to DST.

Ditto on FreeBSD 4.7:
echo mktime(0, 0, 0, 3, 29, 2003) . "\n";
echo mktime(0, 0, 0, 3, 30, 2003) . "\n";
echo mktime(0, 0, 0, 3, 31, 2003) . "\n";
gives:
1048896000
-3662
1049065200
This from a machine in the UK, where we switched to DST
on the date in question.

I have a very similar problem to this but with much more severe
symptoms.
