Your logic is fallacious. The following code works and displays invalid
times:
<?php
$success = 0;
$failed = 0;
for ($ts = 0; $ts < 2600; ++$ts)
{
$time = sprintf("%04.4u",$ts);
$result = (strtotime($time));
if ($result)
++$success;
else {
++$failed;
printf("%s failed\n", $time);
}
}
printf("%u Successful cases, %u failures\n",$success,$failed);
?>
