Most anti-wear additives don't really start working until 80C. This is where the oil I'd protecting not the bulk temperature though.
Zddp in oil forms the sacraficial phosphate layers on engine parts like camshafts.
In terms of viscosity, it is important for the engine to warm up and 'thin out' for areas like bearings and piston rings/liners.
As for time, 10mins plus is normal.
