kafka 0.8.2.1 getOffsetsBefore API returning correct offset given timestamp in unix epoch format

I am seeing unexpected behavior in the getOffsetsBefore method of the client API.

I understand the granularity of 'start-from-offset' via kafka spout is based on how many log segments you have.

I have created a demo program that repro's this on my
git hub account [ https://github.com/buildlackey/kafkaOffsetBug/blob/master/README.md ],
and I have also posted this same question to stack overflow with
a detailed set of steps for how to repro this issue
(using my test program and scripts).

See: http://stackoverflow.com/questions/42775128/kafka-0-8-2-1-getoffsetsbefore-api-returning-correct-offset-given-timestamp-in-u

Thanks in advance for your help !
