Varun Saxena commented on YARN-4238:
------------------------------------

[~sjlee0], if modified time is only for debugging, is there any need to filter 
rows based on it ?
Maybe we can remove it.

We can simply fill it on the basis of cell timestamps then and return it back 
in response.
One thing though. The cell timestamps for metrics are filled based on what 's 
reported from client

> createdTime and modifiedTime is not reported while publishing entities to 
> ATSv2

> While publishing entities from RM and elsewhere we are not sending created 
> time. For instance, created time in TimelineServiceV2Publisher class and for 
> other entities in other such similar classes is not updated. We can easily 
> update created time when sending application created event. Likewise for 
> modification time on every write.
