Turn up on time at place (3)
I believe the answer is:
put
'place' is the definition.
('put' can be a synonym of 'place')
'turn up on time' is the wordplay.
'turn' shows that the letters should be reversed in order.
'up on' becomes 'up' ('up' can be similar in meaning to 'up on').
'time' becomes 't'.
'up' in reverse letter order is 'pu'.
'pu'+'t'='PUT'
'at' is the link.
(Other definitions for put that I've seen before include "Place, lay" , "Set (in place)" , "Place in a location" , "Place; placed" , "Place in a position" .)
