If you determine you need 30 minutes to get the amount of water you need on a particular zone, set the run time to 15 minutes and have two start times (or 10 minutes and 3 start times). Space the start times so that the ground can absorb the water.

What I do is set program A for my lawn (zones 2, 3, 4, and 5) and have 2 start times (3am and 5am), 2 days a week. I set program B for my shrubs (zone 1) and have 2 start times (6:15am and 6:45am) three times a week.

No one is allowed to water more than twice a week. Several people have said they water 3 times a week.
