At university prom ahead of time (2,5)

I believe the answer is:

up front

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

'time' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'at university prom ahead' is the wordplay.
'at university' becomes 'up' ('up' can mean studying at university).
'prom ahead' becomes 'front' (I can't explain this - if you can you should give a lot more credence to this answer).
'up'+'front'='UP-FRONT'

'of' acts as a link.

Can you help me to learn more?

(Another definition for up front that I've seen is " Honest - paid in advance".)

I've seen this clue in The Independent.
