NullArgument emitted for `new DateTime(null, new DateTimeZone('America/Los_Angeles'))`

[TysonAndre]

It's possible to suppress or work around this by writing 'now' or suppressing it, but it is working code with examples in official documentation https://www.php.net/manual/en/datetime.construct.php

// Current date/time in the specified time zone.
$date = new DateTime(null, new DateTimeZone('Pacific/Nauru'));
echo $date->format('Y-m-d H:i:sP') . "\n";
