Time before event to get pint maybe for bird (6)

I believe the answer is:

evejar

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

'get pint maybe for bird' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'time before event' is the wordplay.
'time before' becomes 'eve' (I've seen this in another clue).
'event' becomes 'jar' (jar is a kind of event).
'eve'+'jar'='EVEJAR'

'to' is the link.

Can you help me to learn more?

I've seen this clue in The Telegraph.
