Not all the ravages are due to time! (4)

I believe the answer is:

ages

'to time' is the definition.
(ages can informally mean a long period)

'not all the ravages are due' is the wordplay.
'not all' says the answer is hidden in the clue (only some of the letters).
'AGES' can be found hidden inside 'ravages due'.

(Other definitions for ages that I've seen before include "Donkey's years" , "Epochs" , "Times" , "Matures" , "Indefinitely long time" .)

I've seen this clue in the Evening Standard.
