Rates adjusted after sailor gets up-to-date (7)
I believe the answer is:
abreast
'up-to-date' is the definition.
(thesaurus)
'rates adjusted after sailor' is the wordplay.
'adjusted' indicates an anagram.
'after' is a charade indicator (letters next to each other).
'sailor' becomes 'ab' (abbreviation for able seaman).
'rates' anagrammed gives 'reast'.
'reast' after 'ab' is 'ABREAST'.
'gets' acts as a link.
(Other definitions for abreast that I've seen before include "to be up to date" , "Level or keeping pace with" , "Well-informed" , "Side by side - in the picture" , "Level in line" .)
