Being in the sun before noon, and time around it (4-2)

'being in the sun' is the definition.
'Amen-Ra' can be an answer for 'sun' (thesaurus). I am unsure of the 'being in the' bit.

'before noon and time around it' is the wordplay.
'before noon' becomes 'am' (as in AM on a clock).
'and' becomes 'n' (common abbreviation for 'and').
'time' becomes 'era' (era is a kind of time).
'around it' means one lot of letters goes inside another.
'n' placed within 'era' is 'enra'.
'am'+'enra'='AMEN-RA'
