Jean-Daniel Cryans commented on HBASE-1014:
-------------------------------------------

If clients are located in different timezones, then it is already a problem since an update that you just did could be in that client's future. So IMO that we set it on the client or not, having a client in a different timezone is always a problem. But setting it in the client do solve the problem of returning the timestamps in a batched commit without immediate flush.

> The commit(BatchUpdate) and commit(list<BatchUpdate>) should return timestamp that BatchUpdate was committed with (in the case of commit(list<BatchUpdate> should return array of timestamps). 
> This should reduce number of round trips and improve performance in update operations.
