Great times (4)

I believe the answer is:

eras

'great times' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for eras that I've seen before include "At least two times" , "Epochs" , "Periods, ages" , "Long and distinct periods of history" , "Periods of time" .)

I've seen this clue in the Evening Standard and The Wall Street Journal.
