Done.

+//
+// See ash::NightLightController::ScheduleType.
+const char kNightLightScheduleType[] = "ash.night_light.schedule_type";
+
+// Integer prefs storing the start and end times of the automatic schedule at
+// which NightLight turns on and off respectively when the schedule type is set
+// to a custom schedule. The times are represented as the number of minutes from
+// 00:00 (12:00 AM) regardless of the date or the timezone.
+// See ash::NightLightTime.
