Naturally, heartless lad isn't transported home - about time (2,8)

'naturally heartless lad isn't transported' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'home about time' is the wordplay.
I cannot quite see how this works, but
'home' could be 'in' ('he's home' can mean 'he's in') and 'in' is found within the answer.
'about' could be 'c' (circa) and 'c' is found in the answer.
'time' could be 't' (abbreviation) and 't' is found in the answer.
This explanation may well be incorrect...
