Could be a late romp lasting for a certain time (8)

I believe the answer is:

temporal

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

'lasting for a certain time' is the definition.
I can't tell whether this defines the answer.

'could be a late romp' is the wordplay.
'could be' indicates an anagram.
'late'+'romp'='lateromp'
'lateromp' is an anagram of 'TEMPORAL'.

Can you help me to learn more?

(Other definitions for temporal that I've seen before include "Secular; of the temples" , "Worldly, secular" , "profane" , "Not eternal" , "Passing" .)

I've seen this clue in The Irish Independent.
