currently alerts (sent to SLACK but probably other formats as well) reads this:

Project: OS1

Organization: SE Atlas

CLOSED
Host is down
OS1-g-shard-18-05.bxxxxq.gcp.mongodb.net
Created: 2020/06/11 03:44 BST

Type: Mongos

It would be helpful to also include:
Closed: 2020/06/11 07:44 BST
Duration: 1h 53m

As the slack is usually set to each users timezone it creates a confusion when one is looking at how long issue lasted.
This should be easy to implement and it would improve end user experience a lot.

Same would be nice on Atlas 'closed alerts' tab - there seems to be no way currently to get more details about each alerts including when the alert started (only shows when alert was resolved)

Thanks
