Real-Time Clock
You can use the real-time clock on the SmartServer to schedule events to start or stop based on the
calculated sundown or sunrise, or a configured amount of time before or after the sundown or sunrise.
The real-time clock includes an astronomical position sensor that calculates the position of the sun
based on the time-of-day stored on the SmartServer and the location (geographic coordinates) of the
SmartServer, which you specify. Based on the calculated position of the sun, the real-time clock can
determine the sunrise and sundown times and pass this information to the Schedulers on the
SmartServer.

Overview of the Real-Time Clock XML File
The #8000010128000000[4].UFPTrealTimeClock.xml file stores the configuration of the real-time
clock on the SmartServer. You can create multiple real-time clocks; however, the SmartServer
supports only 1 active real-time clock at a time. The following represents a sample
#8000010128000000[4].UFPTrealTimeClock.xml file for a SmartServer:
App/Node
Object/nviTimeSet
11.2
Creating and Modifying the Real-Time Clock XML File
You can create and manage the #8000010128000000[4].UFPTrealTimeClock.xml file with the Set
SOAP function. The following section, Real-Time Clock SOAP Interface, describes how to use Set
and the other SOAP functions provided for the real-time clock application.
