Saint's time in east (9)

I believe the answer is:

augustine

I'm a little stuck... Click here to teach me more about this clue!

'saint's' is the definition.
(I've seen this before)

'time in east' is the wordplay.
'time' becomes 'august' (I am not sure about this - if you are sure you should believe this answer much more).
'east' becomes 'E' (synonyms).
'august'+'in'+'e'='AUGUSTINE'

Can you help me to learn more?

(Other definitions for augustine that I've seen before include "Missionary" , "First Archbishop of Canterbury" , "Saint" , "Friar" .)

I've seen this clue in the Sydney Morning Herald.
