Better cafeteria opening hours
Right now, the opening hours are formatted like this:
- "öffnet um 13:00"
- "öffnet um unbekannt"
- "opens at 13:00"
- "opens at unknown"
Here are a few suggestions:
- Say "1 PM" instead of "13:00" for the English locale
- Put "Uhr" behind the hour for the German locale
- Pick a nicer text for unknown opening times (e.g. "opening time unknown")
