Description:
------------
---
From manual page: https://php.net/intldateformatter.parse
---
Passing a totally wrong datetime format returns a valid but strange datetime despite the date formats being so different.

e.g. 2019-12-10 10:10:00 becomes 2016-06-10 09:10:00

If the date format is wrong to start with, should it not return null?

Test script:
---------------
use IntlDateFormatter;
$formatter = new IntlDateFormatter('en_GB', 3, 3, 'Europe/London', 0, null);
$date = '2019-12-10 10:10:00';
echo date('Y-m-d H:i:s', $formatter->parse($date));

Expected result:
----------------
null

Actual result:
--------------
2016-06-10 09:10:00

Experienced a similar problem.

For example:
- with 'en_US' locale the function returns false.
- with 'de_DE' returns a timestamp which points with 8 years and a few months later.
