Time allocated to worshipping flock by upper circle (3,4)
I believe the answer is:
god slot
'time allocated to worshipping' is the definition.
'flock by upper circle' is the wordplay.
I cannot quite see how this works, but
'circle' could be 'lot' (synonyms) and 'lot' is found within the answer.
The remaining letters 'gods' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for god slot that I've seen before include "when faithful audience is catered for" , "Space reserved on TV" .)
