Likewise, advisor regularly devours Times (5)
I believe the answer is:
ditto
'likewise' is the definition.
(thesaurus)
'advisor regularly devours times' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'devours' is an insertion indicator (I've seen this in other clues).
'times' becomes 'tt' (two abbreviations for time).
The alternating letters of 'advisor' are 'dio'.
'dio' going around 'tt' is 'DITTO'.
(Other definitions for ditto that I've seen before include "couple of marks" , "that which has been said" , "Two dots say same again" , "Duplicate" , "The same thing" .)
