> I've noticed it in a few places in the code... 
> currentMillis can go backwards and have other artifacts.
> nanoTime should be used for intervals (see 
> [https://docs.oracle.com/javase/7/docs/api/java/lang/System.html#nanoTime()|https://docs.oracle.com/javase/7/docs/api/java/lang/System.html#nanoTime()]
>  ) unless it's both the case that the calls are frequent and nanoTime will 
> result in perf overhead, and also that artifacts from negative intervals and 
> such are relatively harmless or possible to work around in the code.
