Steam it off, now and then (7)

I believe the answer is:

attimes

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

'and then' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'steam it off' is the wordplay.
'off' indicates an anagram.
'steam'+'it'='steamit'
'steamit' with letters rearranged gives 'ATTIMES'.

'now' is the link.

Can you help me to learn more?
