Model has a little time in place of worship (8)
I believe the answer is:
template
'model' is the definition.
(template is a kind of model)
'a little time in place of worship' is the wordplay.
'little time' becomes 't' (abbreviation for time).
'in' indicates putting letters inside.
'place of worship' becomes 'temple' (temple is a kind of place of worship**).
'a'+'t'='at'
'at' going inside 'temple' is 'TEMPLATE'.
'has' acts as a link.
(Other definitions for template that I've seen before include "Pattern or mould" , "original design" , "Shaped pattern" , "Shape serving as model" , "Pattern, model" .)
