> Improvement: Support  rewind by time  !
> My scenarios as follow:
>        A program read record from kafka  and process  then write to a dir in HDFS like /hive/year=xxxx/month=xx/day=xx/hour=10 .  If  the program goes down . I can restart it , so it read from last offset . 
>     But  what if the program was config with wrong params , so I need remove  dir hour=10 and reconfig my program and  I  need to find  the offset where hour=10 start  , but now I can't do this.
> And there are many  scenarios like this.
> so , can we  add  a time  partition , so  we can rewind by time ?
