tz_world is a library that maps a location (lat, lng) to a timezone.
From time-to-time the base data in timzone_boundary_builder is updated based upon updates to the IANA timezone database.
With the IANA timezone database
being updated to version 2020a
on April 23rd, timezone_boundary_builder
has now also updated its release.
For current users of tz_world
you can update the data source in two ways:
- Run
mix tz_world.update
- In a running system, call
TzWorld.reload_timezone_data/0
. Application restart is not required - the new data is downloaded and installed in the running system.
