Snooze will delay your wake up if you do not feel rested at alarm time.
After hitting a snooze button on the alarm screen, you get an additional period of sleep, and the alarm time is postponed.
You can also limit snoozing in several ways to prevent oversleeping.

The alarm goes off at 5:30, and it wakes you up at 5:33.
