I found these snippets:

https://psalm.dev/r/4bf2f97a7e

<?php

function createDate(): DateTime
{
    $tz = new DateTimeZone('GMT-7');
    return new DateTime(timezone: $tz);
}

Psalm output (using commit ef3b018):

ERROR: InvalidNamedArgument - 6:25 - Parameter $timezone does not exist on function DateTime::__construct
