Description:
------------
IntlDateFormatter appears to treat the provided pattern parameter 'MM/dd/yyyy h:mm: a' as invalid based on the given culture.  The problem occurs after a change in ICU 64.1 to no longer accept am/pm for cultures with the languages 'es', 'sv' and several others. 

Should the IntlDateFormatter be able to parse from a standard pattern independent of the set locale?

Test script:
---------------
<?php
$date = '08/08/2019 06:00 pm';
$cultureZones = [
'en_US' => 'US/Central',
'es_US' => 'US/Central',
'fr_CA' => 'Canada/Central',
'en_CA' => 'Canada/Central',
'es_ES' => 'Europe/Madrid',
'en_GB' => 'Europe/London',
'es_MX' => 'America/Mexico_City',
'fr_FR' => 'Europe/Paris',
'sv_SE' => 'Europe/Stockholm'
];
foreach($cultureZones as $culture => $timezone) {
$formatter = new \IntlDateFormatter($culture, 2, 2, $timezone, 1, 'MM/dd/yyyy h:mm a');
echo $culture." (".$timezone.") returned: ".var_export( $formatter->parse($date), true )."\n";
}

Expected result:
----------------
en_US (US/Central) returned: 1565305200
es_US (US/Central) returned: 1565305200
fr_CA (Canada/Central) returned: 1565305200
en_CA (Canada/Central) returned: 1565305200
es_ES (Europe/Madrid) returned: 1565280000
en_GB (Europe/London) returned: 1565283600
es_MX (America/Mexico_City) returned: 1565305200
fr_FR (Europe/Paris) returned: 1565280000
sv_SE (Europe/Stockholm) returned: 1565280000

Actual result:
--------------
en_US (US/Central) returned: 1565305200
es_US (US/Central) returned: false
fr_CA (Canada/Central) returned: 1565305200
en_CA (Canada/Central) returned: 1565305200
es_ES (Europe/Madrid) returned: false
en_GB (Europe/London) returned: 1565283600
es_MX (America/Mexico_City) returned: false
fr_FR (Europe/Paris) returned: 1565280000
sv_SE (Europe/Stockholm) returned: false

I would say no, but regardless this is something you would have to request of the ICU project - not PHP. We merely provide a wrapper around their library.

Note that if you're parsing date strings in the "MM/dd/yyyy h:mm a" (aka "m/d/Y H:i a") format then you can, and probably should, skip IntlDateFormatter::parse() and use regular old strtotime/DateTime instead. The intl stuff handles locale differences, and if you don't need or want locale handling...

In this case, it is a framework that is calling the IntlDateFormatter for the reverse transform operation.
