I meant to upset? Never! (2,2,4)

I believe the answer is:

at no time

'never' is the definition.
('at no time' can be a synonym of 'never')

'i meant to upset?' is the wordplay.
'upset?' indicates anagramming the letters (I've seen 'upsets' mean this).
'i'+'meant'+'to'='imeantto'
'imeantto' with letters rearranged gives 'AT NO TIME'.

(Another definition for at no time that I've seen is " Never".)

I've seen this clue in The Telegraph.
