Ron is looking for the oldest date, what seems to be the same as the
earliest date. Anyhow, otherwise one could use rsort() instead of sort().
Accessing by numeric index is possible after either sorting, because
both functions don't keep the keys (contrary to asort() and arsort()):
$array = [
'es-PR' => '2014-11-04 08:22:07',
'en-US' => '2009-04-05 09:00:00',
'es-MX' => '2014-11-08 02:25:40'
];
sort($array);
var_dump($array);
