Vrushali C commented on YARN-4238:
----------------------------------

[~gtCarrera9] ,
[~varun_saxena] mentioned that he most probably recollects that the modified time was being used to query the in memory store in ats v1. Do you have any idea if that was for Tez? Do you know if Tez specifically needs entities back in some chronological order?  Do you think we should email them and check? 

If that is the case, we do need the modification time class member. Then we perhaps can go ahead with updating it in each setter function in the TimelineEntity class.

> 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.
