In consequence good time promised (7)
I believe the answer is:
engaged
'promised' is the definition.
(synonyms)
'in consequence good time' is the wordplay.
'in' indicates putting letters inside.
'consequence' becomes 'end' (I've seen this in another clue).
'good' becomes 'g' (abbreviation).
'time' becomes 'age' (an age is a period of time).
'g'+'age'='gage'
'end' enclosing 'gage' is 'ENGAGED'.
(Other definitions for engaged that I've seen before include "prior to one's marriage" , "Fully committed - to get married?" , "Taken on - betrothed" , "In use" , "Occupied with business - about to marry?" .)
