Bug description: mktime returns incorrect values for some years
mktime() should return 86400 (the number of seconds in a
day) for the following calculations. For some years (1972,
1978, 1989, 1995, 2000, etc.) it returns 90000 instead of
86400. The following code will demonstrate this.
<?php
function
mktime_test ()
{
for ($i = 0; $i < 100; ++$i)
{
/* $timestamp should = 86400. (ie: 60 x 60 x 24). */
$timestamp = mktime (0,0,0,10,30,$i) - mktime
(0,0,0,10,29,$i);
if ($i < 10)
{
$year = "200" . $i;
}
else if ($i < 70)
{
$year = "20" . $i;
}
else
{
$year = "19" . $i;
}
printf ("
$year - $timestamp<br>
");
}
}
mktime_test ();
?>
