It would be great to have a node with the timezone (like "Europe/Berlin") for a location in the Nominatim result object.

I too would like this. We could use it in GNOME to do reverse geocoding of the computer's location to a timezone, so that we could automatically update the timezone when the user has travelled to another country.

This isn't really the core business of OSM. There are external sources available you can use to enhance the results with timezone data.

Which external sources do you have in mind? And do they have similar open data objectives as OSM?

I was thinking of the tz database that you could mingle with geocoding results.

Let me clearify my earlier statement: first of all, I'm not aware that a consensus has been reached regarding time zone mapping. Some boundaries seem to have a timezone tag now which might be usable but requires resolving the timezone info of the complete hierarchy, not impossible but not trivial either. Second, I wouldn't consider time zone estimation a primary task of a geocoding server and using it primarily for time zone resolution sounds like overkill. Third, it should be easy enough to create a small timezone dataset that can be efficiently queried locally. So even if it might be an interesting feature, it will be so close to the end of a very long list of features to implement that 'wontfix' is closer to the truth than anything else. But by all means, prove me wrong and send a patch.

There is more or less a consensus in the OSM community that timezones don't belong into OSM. So, same goes for Nominatim. It simply won't happen.
