Use the formatDateTime function to change the date into a string with the time zone. See documentation here: https://docs.mendix.com/refguide/parse-and-format-date-function-calls
So use something like
formatDateTime($yourDate,'EEE, d MMM yyyy HH:mm:ss Z')
This will result in
'Sun, 8 Jun 2008 10:12:01 +0200'
And that makes it human readable with the timezone.
