This is a Rust library for handling date and time, particularly suitable for dealing with the troublesome scenarios of time zones and daylight saving time. It offers a simple and user-friendly API with robust time zone support, capable of automatically handling time zone conversions, daylight saving time adjustments, and losslessly formatting and parsing dates and times. This project is a new creation by the author of the well-known regular expression tool 'rg' (ripgrep), and is currently in the development phase, so it is advised to be cautious when using in a production environment.
