All rotor nozzles are different GMP (gallon per minute) and interchangeable. No times will be the same for all homes or even each zone.
A corner rotor that only turns 90deg can have a less GPM nozzle than one that turns 180deg.
To find the optimal time for each zone, place 5-6 shallow cans (tuna size) spread out around the zone.
They should collect 1/2"-3/4" water each watering.
If you take the steps to fine tune your system you can save water.
Note most irrigation companies won't do this, and just leave in whatever GMP nozzle comes with the rotor.
Lots of info online about tuning a system.
