"When will u b here?" (3)

I believe the answer is:

eta

(Other definitions for eta that I've seen before include "When one is due" , "character abroad?" , "when it might reach us?" , "giving expected termination of journey" , "Militant Basque organisation - Greek letter" .)

I've seen this clue in The New York Times, the Universal and the LA Times.
