MPPT controller setup question

I haven't received my Tracer 4210rn charge controller yet but I downloaded the manual and it seems very straight forward except for the timers.

There are two timers I have to set one is "load will be on for x # of hours since sunset" and "load will be off for x # hours before sunrise"

I'm guessing the controller turns itself on/off by itself?

How does it know the times of sunrise sunset?

You probably will not use load control or the related timers.

Controller knows sunrise and sun set by monitoring solar input. Default is 10 hour night and will adjust as it learns the voltage cycle. See section 4.4 page 15.
