Possibly pleased to have passed (7)
I believe the answer is:
elapsed
'passed' is the definition.
('elapse' can be a synonym of 'pass')
'possibly pleased' is the wordplay.
'possibly' is an anagram indicator.
'pleased' anagrammed gives 'ELAPSED'.
'to have' acts as a link.
(Other definitions for elapsed that I've seen before include "Pleased to have passed" , "Expired" , "slipped away" , "Went by" , "Passed, of time" .)
