Hello all, I've changed to TimeBasedRollingPolicy test case to make it faster. It used to test the rolling functionality with real time intervals. Now we use a subclass of TimeBasedRollingPolicy in which we inject time when needed. The test case now runs in a fraction of a second instead of taking around 10 seconds.
