Wanted to bring this to the attention of the group in hopes of getting some votes added to the idea, and to get some attention from Lightning PMs. We are in the throes of migrating to Lightning, and one huge problem keeps coming up with our users: Relative Date Displays. Especially in a time-sensitive service environment, having precision of dates is imperative to our users, and Chatter and the chronological Feed View currently do not give us that. Seeing '16 hours ago' on multiple entries in the feed can really lead to confusion.

PLEASE UPVOTE: https://success.salesforce.com/ideaView?id=0873A000000CVvCQAW

Also wanted add in a few PMs for visibility, and I apologize fro throwing darts at a board here. @Jean-Baptiste Minchelli @Kelly Vida @David Green @Alex Edelstein @Xander Mitman
