Thanks for sharing. I liked the short video.

These have been around for a few years. Wonder what people built with them since. Anyone know of any popular distributed systems using them nowadays? (I noticed the company the author mentioned shut down https://medium.com/@MeetLima/this-time-its-goodbye-5573a97be...)

As an additional resource I liked the description of ITC by Fred Hebert: https://ferd.ca/interval-tree-clocks.html. He is the author of the wonderful Learn You Some Erlang book. There is an ITC library he maintains as well: https://github.com/ferd/interval-tree-clocks, started by Paulo Sergio Almeida.
