What it does | A Sunrise/Sunset microblock calculates the time the sun will rise and set based on location and time zone information entered in the EIKON® application or on the Properties page. The sunrise and sunset outputs produce today's sunrise and sunset times. The output values are in minutes since midnight. The daylight output turns on when the current time falls between sunrise and sunset and turns off when the current time is before sunrise or after sunset.
