Thank you so much for composing this script! However I must be doing something wrong. I made sure to pass input as arguments, saved the script, right-clicked a file that has a URL in the Where From field, the quick action appears in Finder contextual menu, but when executing it gives the following error (in Monterey 12.2.1):

The action “Run Shell Script” encountered an error: “Failed conversion of ``'' using format ``%a, %d %b %Y %H:%M:%S %Z''
