He needs to look around for a short time (5)

I believe the answer is:
peter
'he' is the definition.
(I've seen this before)
'to look around for a short time' is the wordplay.
'to look' becomes 'spy' (spy can mean to look or see).
'around' says to take the centre.
'for' means one lot of letters go next to another.
'a short time' becomes 'eter' (I can't explain this - if you can you should give a lot more credence to this answer).
The centre of 'spy' is 'p'.
'p'+'eter'='PETER'
'needs' acts as a link.
Can you help me to learn more?
(Other definitions for peter that I've seen before include "Leader of the Apostles" , "foundation for church" , "Dwindle away to nothing" , "Man's name" , "- Sellers, twentieth century English comedian" .)
