William Burns commented on ISPN-4733:
-------------------------------------

This was fixed in core already by https://github.com/infinispan/infinispan/blob/220e3cc066f18a153c003e112b3587f376199bf9/core/src/main/java/org/infinispan/util/DefaultTimeService.java.  However there is an issue with some test files.

> {{System.nanoTime()}} can overflow, so it's not ok to compare two {{System.nanoTime()}} return values directly. Instead, we always have to work with the difference between return values.
