The time Andy got pointlessly upset (3)
I believe the answer is:
day
'the time' is the definition.
(day is a kind of time)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for day that I've seen before include "THIRD PART OF 23" , "Period of time" , "24 23 acrosses" , "24 hour period" , "Dawn to dusk" .)
