Not that tiny now (4,6)

I believe the answer is:

this minute

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

'not that tiny' is the wordplay.
'not that' becomes 'this' (this one as opposed to that one).
'tiny' becomes 'minute' (minute can mean small).
'this'+'minute'='THIS MINUTE'

(Another definition for this minute that I've seen is " At once".)

I've seen this clue in The Guardian.
