Geodetic system?

First off - thank you for writing this library. It's perfect for quick timezone determination of remote/mobile IoT devices.

My question:
What geodetic system is this library using for latitude/longitude comparisons against the timezone shape files?

Thank you for the feedback and starting the discussion. This package uses the timezone boundary data from here: https://github.com/evansiroky/timezone-boundary-builder/releases

I believe information about the geodetic system in use can be found there.

Thanks for the response - I reached out to the folks at timezone-boundary-builder and got an answer for us.

For anyone else with the same question - TimezoneFinder adheres to the geodetic system used by timezone-boundary-builder, which uses WGS84 as its geodetic system. See link below for the discussion on timezone-boundary-builder's repo.
