Diablo – the purpose of the “Death Clock” during boss fights

diablo-3

When everyone dies in a party during a boss fight, a red timer starting at 1 minute appears near their corpse and counts down. What is the purpose of this timer?

I imagine that is how long a party has to do something before the boss resets, but what can be done? There is no way to revive during a boss fight without another player's help.

Damage over time spells could still be on the boss, if it is a close fight it might be enough to take him out. I have not had it happen vs a boss but i have seen champion packs die due to my WD dots after I died my self.
