Bug description: possible mktime bug?
Description:
------------
I'm not really fond of mktime() but I needed a way of taking two dates in
MySQL format and seeing which date is older... ie:
$date = "2007-03-01";
if ($date <= date('Y-m-d'))
{
print "Expired";
} else {
print "Not Expired";
}
I know you can't use dates like that in the condition so I used date('U')
and mktime() to give me the seconds since the Unix Epoch but I decided to
test using different date formats first just to see how mktime handles
months and years that might or might not have leading zero's.. notice the
difference in seconds with the year 08 vs. 07
please correct me if I'm doing something stupid here that I should not be
doing.
I don't quite understand Bug #25050 - is this the same situation?
thanks for your time!
Reproduce code:
---------------
print "test1: " . date('U', mktime(0, 0, 0, 3, 1, 2008)) . "<br />"; //

print "test2: " . date('U', mktime(0, 0, 0, 3, 1, 08)) . "<br />"; //
3-1-08 returned 951800400
print "test3: " . date('U', mktime(0, 0, 0, 03, 1, 2008)) . "<br />"; //
03-1-2008 returned 1204261200
print "test4: " . date('U', mktime(0, 0, 0, 03, 1, 08)) . "<br />"; //
