> Project: Apache Apex Malhar

>
> Time Based Dedup has timeExpression as optional. It has to be supplied by the
> user.
> In the current setting, if the user does not specify a timeExpression, then a
> different time (System time) will be passed for each tuple, irrespective of
> whether the tuple is a duplicate or a unique. This is a bug since even the
> duplicate tuples may fall in different buckets and will be concluded as
> unique.
