5288696 Tipton Airport is:
* Located in United States (US) -> Maryland (MD) -> Anne Arundel County (003)
* Tagged with time zone America/Phoenix (UTC-7) (I have changed it in the web frontend)

4347283 Anne Arundel County is:
* Tagged with time zone America/New_York (US) (UTC-4/5)

Is there any form of checks when the timezone on a point differs from the time zone on it's most specific hierachy?

Below are three lists of potential problematic points.
Disclaimers:
1) I haven't checked them all to see if they are false positives.
2) The data might be sligthly mixed with other data sources.


Here's a list on 310 airports, where the timezone on GeoNames differs from the time zone found on the coordinate using https://github.com/mj1856/GeoTimeZone
