3 zones 12 hours?!

Thank you, sir. So currently I have in zone 1 a An agave with a variety of succulent plants and 5 rosemary shrubs. This area is about 60-75 square feet in an inverted L this zone on a even day watering schedule is saying to water 1 hr fifty minutes for this zone. Zone two has a variety of succulents and a olive tree. Area is about 20-30 square feet. It’s suggesting 1 hour 36 minutes even days. Zone 3 has about 14 Carolina cherry hedge trees, 1 olive and a A few ligustrum. It’s recommending 2 hours 24 minutes. I think it’s basically 13 hours a week I take it?
