'Wikidata: Filter post codes only current valid

I would like to filter post codes to show only the current active for today.

Problem is there are are cities with old post codes (Example).

My current query shows the old post codes:

SELECT ?city ?cityLabel ?postcode ?federal_stateLabel ?federal_state_nr WHERE {
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],de". }
  ?city (wdt:P31/(wdt:P279*)) wd:Q7930989;
    wdt:P17 wd:Q183;
    wdt:P281 ?postcode;
    wdt:P131 ?federal_state.
  ?federal_state wdt:P439 ?federal_state_nr.
}
ORDER BY (?postcode)
LIMIT 10

(query.wikidata.org)

I would have to use start time P580 and end time P582 but I don't see how.
