Paper finished? Stop working! (5,2)

Ross

I believe the answer is:

times up

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

'stop working' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'paper finished?' is the wordplay.
'paper' becomes 'times' (The Times newspaper).
'finished?' becomes 'up' (eg 'time's up' means the time is finished).
'times'+'up'='TIMES UP'

Can you help me to learn more?

(Other definitions for times up that I've seen before include "feminist campaign" , "Stop working!" .)

I've seen this clue in The Sun.
