Time between being at home and travel abroad (8)
I believe the answer is:
Here is my best explanation:
'time between' is the definition.
(I've seen this before)
'at home and travel abroad' is the subsidiary indication.
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'and' says to put letters next to each other.
'abroad' is an anagram indicator.
'travel' is an anagram of 'terval'.
'being' is the link.
(Other definitions for interval that I've seen before include "Gap during performance", "Pause (between acts)", "Travel in (anag.)", "Time between two events", "Hiatus", "Pause; pitch difference", "Break, pause", "Short break", "breather" and "A break in a play".)
