question: private void assertTimestampsEqualWithEpsilon ( long expected , long actual , int epsilon , String desc ) { assertTrue ( "Expected a " + desc + " time within " + epsilon + "ms of " + expected + " but got " + actual , Math . abs ( actual - expected ) < epsilon ) ; }
target:  Kinda like the JUnit asserts for doubles, which allows an "epsilon" But this is for integers, and with a specific description in the assert just for timestamps. All times are expected in milliseconds
