Get rid of command, having lost time after time (9)
I believe the answer is:
eradicate
'get rid of' is the definition.
(thesaurus)
'command having lost time after time' is the wordplay.
'command' becomes 'dictate' (I've seen this before).
'having lost' is a deletion indicator.
'time' becomes 't'.
'after' says to put letters next to each other.
'time' becomes 'era' (I've seen this before**).
'dictate' with 't' removed is 'dicate'.
'dicate' after 'era' is 'ERADICATE'.
(Other definitions for eradicate that I've seen before include "Extinguish, wipe out" , "Kill" , "Get rid of, eliminate entirely" , "Destroy completely" , "Exterminate, extinguish" .)
