It's worth getting the wrong time about right! (5)
I believe the answer is:
merit
'it's worth' is the definition.
(merit is a kind of worth)
'the wrong time about right' is the wordplay.
'the wrong' indicates an anagram.
'about' indicates putting letters inside.
'right' becomes 'r' (common abbreviation).
'time' with letters rearranged gives 'meit'.
'meit' placed around 'r' is 'MERIT'.
'getting' is the link.
(Other definitions for merit that I've seen before include "credit" , "The M in OM" , "Deserve; excellence" , "Goodness" , "Just deserts" .)
