Is no longer dated when done up (3)

Ross

I believe the answer is:

was

'is no longer' is the definition.
(I've seen this before)

'dated when done up' is the wordplay.
'dated' becomes 'saw' ('see' can be a synonym of 'date').
'when done up' says the letters should be written in reverse.
'saw' backwards is 'WAS'.

(Other definitions for was that I've seen before include "Lived" , "(He/she/it) existed" , "(I/he/she/it) existed" , "Did live" , "Used to be" .)

I've seen this clue in The Times.
