tzf

In the past few years, I have developed a few libraries related to converting GPS coordinates to a TZ database timezone. For the Go/Rust/Python version, you can also see the blog post: History of package tzf. Use Case Link Go ringsaturn/tzf Rust ringsaturn/tzf-rs Python ringsaturn/tzfpy Swift ringsaturn/tzf-swift Wasm(browser only) ringsaturn/tzf-wasm PostgreSQL extension ringsaturn/pg-tzf Or online preview: https://ringsaturn.github.io/tzf-web/.

A simple example of how to group world cities by timezone

Developed and released pg-tzf, a PostgreSQL extension providing microsecond-level latitude/longitude to time zone conversion, based on the Rust library tzf-rs and the pgrx framework.

Introduces the evolution of tzf, from the initial implementation in Go, to the later Python extension, and finally to the current Rust implementation with a PyO3 wrapper.
