merlimat opened a new pull request #2628: In ZK 3.4.13 the elapsed time is not anymore based on System.currentTimeMillis()
URL: https://github.com/apache/incubator-pulsar/pull/2628
 
 
   ### Motivation
   
   In ZK dashboard, the latency metrics are showing wrong values (eg: 48 years). 
   
   The problem is that we rely on AspectJ to get access to ZK internals and add instrumentation. The "request start" timestamp in ZK 3.4.13 has been changed from using `System.currentTimeMillis()` to `System.nanoTime() / 100000`. 
   
   We need to change the timestamp we use for end operation as well.
