Downloads and installs the latest Timezone GeoJSON data.

Arguments

• --include-oceans (-o) will include the geojson for the oceans in the downloaded data. The default is to download data without ocean coverage.

• --force (-f) does two things:

  • Forces an update even if the currently installed data is already at the latest release. Useful when switching between including and excluding ocean coverage.
  • Creates the directory configured under :data_dir if it does not yet exist. Without --force a missing :data_dir is reported as an error so a misconfigured :data_dir is loud rather than silently materialised. Pass --force on the first install when you have set a custom :data_dir that is not part of the build artifacts.

• --trace (-t) emits debug-level progress logs (current memory usage, download / extract / parse phases).
