Logger.info("doing work every #{ExDuration.format(@interval_ms, :millisecond)}")

# Format the duration since a timestamp
start = :os.system_time(:millisecond)
_ = work()
Logger.info("work took #{ExDuration.since(start, :millisecond)}")

# Format the duration between two DateTime's
Logger.info("A and B are #{ExDuration.between(dt1, dt2)} apart")
```
