Notice midwife attending someone in wings? How time flies! (9)
I believe the answer is:
clockwise
'attending someone in wings? how time flies' is the definition.
I can't judge whether this defines the answer.
'notice midwife' is the wordplay.
'notice' becomes 'clock' (I've seen this before).
'midwife' becomes 'wise' (I can't justify this - if you can you should give a lot more credence to this answer).
'clock'+'wise'='CLOCKWISE'
Can you help me to learn more?
(Other definitions for clockwise that I've seen before include "movement of hand over face" , "As hands sweep round" , "Moving as hands do?" , "Cow sickle (anag.)" , "Direction of movement on dial" .)
