//For date before 20040318000000 return -1
//After 20040318100000 return timestamp
    if (is_numeric($time) && $time != -1)
        return $time;

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

strtotime doesn\'t support it.

"Borders" of this bug:
'20040318094229'
'20040318094230'

Manual:
Because strtotime() behaves according to GNU date syntax, have a look at the GNU manual page titled Date Input Formats. Described there is valid syntax for the time parameter.

So, neither '20040318094229' nor '20040318094230' are both not valid syntax for the time parameter. But...

Test result:

20040318094231



-1
79200
165600

Test source:
<?php
$date = '20040317';
$h = '00';
$i = '00';
$s = '00';
$t = -1;
while($t == -1) {
    $t = strtotime($date.$h.$i.$s);
    $s++;
    if (strlen($s) == 1) {
        $s = '0'.$s;
    }
    if ($s == 60) {
        $s = 0;
        $i++;
    }
    if (strlen($i) == 1) {
        $i = '0'.$i;
    }
    if ($i ==  60) {
        $i = 0;
        $h++;
    }
    if (strlen($h) == 1) {
        $h = '0'.$h;
    }
    if ($h == 24) {
        $h = 0;
        $date++;
    }
    if ($date == 20040319) {
        break;
    }
}
echo $date.$h.$i.$s;
echo '<br>';
echo '<br>';
echo '<br>';
echo '<br>';
echo strtotime('20040318094229');
echo '<br>';
echo strtotime('20040318094230');
echo '<br>';
echo strtotime('20040318094231');
?>

P.S. Sorry, I wrote "Actual result" as "Expected result".

As I know, in php 4 and php 5 strtotime do support it. It's wrong.

14-chars mysql timestamps work since PHP 5.1.0.
