Behind the clock (4)

I believe the answer is:

late

'behind the clock' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for late that I've seen before include "Previous" , "on time? Not quite" , "Running behind time" , "Teal (anag.)" , "(Of a person) no longer alive" .)

I've seen this clue in the Evening Standard.
