Date strings to be in correct language

Display the dates in correct language

If we have a multi tenancy site then the PHP language may not be set to the one a person is viewing the site with so that PHP created strings, like a date may be in wrong language, eg

EN 24 July 2022, 08:37
DE 24. July 2022, 08:37

We can't use the PHP setlocale() function because it can cause issues on a multithreaded server

Now that we are including PHP intl module by default we can use some of it's functions to get what we need,

eg:

    $cl = current_language();
    // Remove the '.utf8' from the language
    $cl = preg_replace('/\.utf8$/','',$cl);
    $langobject = datefmt_create($cl, IntlDateFormatter::LONG, IntlDateFormatter::SHORT, null, null, 'dd. MMMM yyyy, hh:HH');
    $langstring = datefmt_format($langobject, 1658651838);
    log_debug($langstring);
