  They don't really bother me. They aren't AI spam, and some folks may enjoy them. It's pretty easy to not click on a link, for me.

  TZ are a fun project. I found that it's difficult to translate a long/lat into a TZ ID, so I wrote this[0].

  Works a charm. It's based on the Timezone Boundary Builder[1].

  I wrote a tutorial on SpatiaLite here: https://datasette.io/tutorials/spatialite - "Building a location to time zone API with SpatiaLite"

  It shows how to use SpatiaLite + Datasette to build an API that can tell you what timezone a latitude/longitude point is in, using data derived from OpenStreetMap via https://github.com/evansiroky/timezone-boundary-builder

  Here's a demo: https://timezones.datasette.io/timezones/by_point?longitude=... - add ".json" to the URL for the JSON output.

  In principle a calendar program could use its output to perform GIS lookups of locations then use the tzinfo DB to get the correct timezone at the given location and specified time.

• How can I get a user's timezone based on location and create a DateTime() based on that timezone?

  You could ask google. Amazon or Microsoft probably offer similar APIs. Or you can do it yourself. It's a very complicated topic, though.

• Big problems at the timezone database

  There is a separate timezone boundary builder which maps geography to timezones using a shapefile, and the shapefile is >35MB uncompressed. By comparison the latest tzdata is 1.2M uncompressed.
