Something that I got used to having with the DBM Spell Timers addon is the fact that you can Shift left click on a cooldown to report the time remaining left on that particular cooldown to the raid along with the spell details and the player the cooldown belongs to. Something along the lines of:

[Raid][Playerx]: Playerx Rebirth: 01:14
[Raid][Playery]: Playery Shield Wall: 00:23
