I found this answer that says UILocalNotification fire time isn't that accurate. I was also going through Apple's documentation on Timer and found this regarding timer tolerance

The system reserves the right to apply a small amount of tolerance to certain timers regardless of the value of the tolerance property.

Since the scheduled notification will be using a timer behind the scenes, the system must be applying a small tolerance to improve power saving. If you want to read more about timer tolerance read this Apple's documentation on timer.
