Stick to this time and this place (6)
I believe the answer is:
adhere
'stick to' is the definition.
(synonyms)
'time and this place' is the wordplay.
'time' becomes 'AD' (AD, Anno Domini, as opposed to BC, Before Christ).
'and' is a charade indicator (letters next to each other).
'this place' becomes 'here' (here in this location).
'ad'+'here'='ADHERE'
'this' acts as a link.
(Other definitions for adhere that I've seen before include "Cling, attach" , "Remain attached" , "Stick to, cling" , "Agree" , "Stick to, remain loyal" .)
