exception when a timestamp string is passed. @tzulitai  @tony810430

> We had a Kinesis user requesting this feature on an offline chat.
> To be specific, we let all initial Kinesis shards be iterated starting from 
> records at the given timestamp.
> The AWS Java SDK we're using already provides API for this, so we can add 
> this functionality with fairly low overhead:
