Reveal end of world is not far away (8)

I believe the answer is:

disclose

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

'reveal' is the definition.
(I know that reveal can be written as disclose)

'end of world is not far away' is the wordplay.
'end of' says to take the final letters.
'not far away' becomes 'close' (I can't justify this - if you can you should believe this answer much more).
The last letter of 'world' is 'd'.
'd'+'is'+'close'='DISCLOSE'

Can you help me to learn more?

(Other definitions for disclose that I've seen before include "Sold ices (anag)" , "Let out" , "Announce" , "Uncover" , "Lay bare" .)

I've seen this clue in The Guardian.
