It's worth getting right in time, possibly (5)
I believe the answer is:
merit
'it's worth' is the definition.
(merit is a kind of worth)
'right in time possibly' is the wordplay.
'right' becomes 'r' (common abbreviation).
'in' means one lot of letters goes inside another.
'possibly' is an anagram indicator.
'time' anagrammed gives 'meit'.
'r' put inside 'meit' is 'MERIT'.
'getting' is the link.
(Other definitions for merit that I've seen before include "Quality deserving reward" , "Good point or quality" , "Excellence, desert" , "of a high order?" , "Excellence, worth" .)
