enterting some values to mktime produces the wrong answer

echo '<?echo mktime (0,0,0,3,31,2002);?>' | php
-3662

echo '<?echo mktime (0,0,0,3,31,2001);?>' | php
985993200

echo '<?echo mktime (0,0,0,3,31,1002);?>' | php
-3662

echo '<?echo mktime (0,0,0,3,31,2);?>' | php
-3662

echo '<?echo mktime (0,0,0,3,32,2);?>' | php
1017615600

I tried it on two machines
both installed today from the FreeBSD Port

I don't have any other versions available to test it

Must be OS specific as this works fine in Linux.

Additional note: Works fine with the LEGAL years, 2002 and 2001, those others in your examples are not legal.

Got the same problem on a FreeBSD4.9 with php4.3.5

Wonder if it isnot a problem with the change of hour ?
(which was the 31 of march in 2002 and the 28th of march in 2004)


echo '<?echo mktime (0,0,0,3,28,2004);?>' | php
-7262
 echo '<?echo mktime (1,0,0,3,28,2004);?>' | php
-3662
 echo '<?echo mktime (2,0,0,3,28,2004);?>' | php
-62
 echo '<?echo mktime (3,0,0,3,28,2004);?>' | php
1080435600  //good
 echo '<?echo mktime (0,0,0,3,29,2004);?>' | php
1080511200 //good
