At first I am curious if such thing exists at all.
What I need is to see the 30 sec. timer (or call it resurrection window) used in battleground resurrection system. It could be a timer to be seen when I am alive or dead, but not released, which would show something like "Next resurrection wave in X sec." with a countdown. Or simply a timer. Or a bar.
Got any ideas about some addon? Or maybe such thing is restricted by Blizz?
I do not believe it is possible to retrieve that information at all.
Often asked for and subsequently stated by more knowledgable members that it cannot be done.
You can read how long the timer is when you are dead. However, there's a randomized delay (I believe) between rezzes and also a randomized delay after a base is taken until the rez timer (re-)starts.
Aah yes, after some googling I probably found a very simple restriction by Blizz:
API GetAreaSpiritHealerTime Gets the time left until the next resurrection cast.
Returns timeleft Integer - Seconds until the Spirit Guide casts its next Area Resurrection. Returns 0 if player is not dead.
