You're welcome in new amenity (3,4)

I believe the answer is:

any time

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

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

'new amenity' is the wordplay.
'new' is an anagram indicator.
'amenity' is an anagram of 'ANY TIME'.

'in' is the link.

Can you help me to learn more?

(Other definitions for any time that I've seen before include "at one's disposal night and day" , "Whenever you like" .)

I've seen this clue in The Independent.
