Security checkValidDateTime

Hi,
in checkValidDateTime of Security the code

if ($len < 10) {
$time = $dateTime;
}
if ($len == 10) {
$date = $dateTime;
} else { // $len > 10

should be modified as

if ($len < 10) {
$time = $dateTime;
} else if ($len == 10) {
$date = $dateTime;
} else { // $len > 10

or the last else will be verified also when len < 10

If you try to validate a datetime having len < 5 you will try tp split a null datetime ...

I think you could better change each
$datetime = null;
with a
return null;
so avoiding processing wrong cases.
Best regards.
