Description:
------------
strtotime() now returns false for input like '12am', where the minutes are omitted with am, pm, a.m. or p.m.

This should be allowed according to the GNU date input formats: http://www.gnu.org/software/tar/manual/html_chapter/tar_7.html#SEC112

It works correctly in 4.3.10, 4.4.0 and 5.0.4.
It fails in 5.1.0RC1, built Aug 16 2005 13:49:49 and 5.1.0RC2-dev, built Oct 6 2005 20:17:56.

Reproduce code:
---------------
<pre><?php

$tests = array(
    '12am', '1am', '1pm',
    '12a.m.', '1a.m.', '1p.m.',
    '12:00am', '1:00am', '1:00pm',
    '12:00a.m.', '1:00a.m.', '1:00p.m.'
);

foreach ($tests as $test) {
    $t = strtotime($test);
    printf("%-10s => %-15s => %s\n", $test, var_export($t, 1), date('r', $t));
}

?></pre>

Expected result:
----------------
12am       => 1128643200      => Fri, 07 Oct 2005 00:00:00 +0000
