Hello,
in one of my projects I need to have a simple and easily testable timer helper, so I came across :chronos which does exactly what I needed.
Since I had some issues (now resolved) with the inclusion of the library in my project, I decided to port it to Elixir (also as an exercise).
The library is here: https://github.com/xadhoom/etimer and I would like to receive any kind of comment and suggestion about it, since is my first lib.
Also if someone finds it useful and decently done, I’ll be glad to publish it over hex.pm
