As a fan of [TimeAPI.io](https://www.timeapi.io/swagger/index.html), but not third party providers in general, I wanted my self-hosted alternative. Basically, with this project I just wanted to create a very simple API that gives me a JSON object with many useful datetime values for a given timezone. The timezone has to be specified in [IANA timezone format](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones#List).
