I’ve just published Astro 1.1.0 with the following changelog entry. Please note the breaking change to configuration (there are no breaking changes to application code).

Breaking Change

  • :tz_world is no longer a required dependency - it is now an optional dependency. This library is used to resolve a time zone name from a given latitude and longitude. When configured, it becomes the default method of resolving time zone names from a location. However it is no possible to provide alternative implementations for this resolution using the :time_zone_resolver option.

  • To retain the previous behaviour, applications should add {:tz_world, "~> 1.0"} to their dependencies.

Enhancements

  • Adds an option :time_zone_resolver to Astro.sunrise/3 and Astro.sunset/3 that is a 1-arity function that is invoked to resolve the time zone name from a given latitude and longitude. The default is to use TzWorld.timezone_at/1 if TzWorld is configured, otherwise an error is returned.

  • The default time zone database is now detected in the following order:

    1. Application.get_env(:elixir, :time_zone_database)
    2. TzData.TimeZoneDatabase if TzData is configured
    3. Tz.TimeZoneDatabase if Tz is configured

Thanks to @cloud8421 for the motivation and encouragement to get this done.
