Note: Sunrise is the time at which the first part of the sun appears above the horizon in the east. At
this time, there is complete light. Sunrise should not be confused with dawn, which is the point at
which the sky begins to lighten, some time before the sun itself appears. Sundown is the time at which
the sun disappears below the horizon in the west. At this time, there is still light, but it begins to
gradually decrease until dusk, which is the point at which darkness falls.
To create events based on the sunrise or sundown, follow these steps:
1. Add a time (SNTP) server to the LAN on which the SmartServer resides, or manually set the time
on the SmartServer using the Setup – Time Web page.

To add a time server to the LAN, follow the instructions in Adding a Time (SNTP) Server to
the LAN in Chapter 3, Configuring and Managing the SmartServer.

To set the time on the SmartServer manually using the Setup – Time Web page, follow the
instructions in Configuring Time Properties in Chapter 3, Configuring and Managing the
SmartServer.
2. Enter the location (geographic coordinates) of your SmartServer in the Real-Time Clock:
Configure Web page following the steps described in the Configuring the Real-Time Clock
section earlier in this chapter.
3. Click the Exception Schedules icon in the Scheduler: Configure Web page. The Scheduler:
Exception Schedules Web page opens.
4. Right-click anywhere in the exception schedule, point to Add Exception, and then click New
One-Time Exception or New Exception on the shortcut menu. If you are creating a one-time
exception, skip to step 6. If you are creating an exception, proceed to step 5.

Create the sundown/sunrise events in a one-time exception to overlap events in the daily
schedule and in other exception schedules with these sundown/sunrise events.

Create the sundown/sunrise events in an exception to replace the daily schedule with the
exception schedule.
See Demonstrating Sunrise and Sundown Events for scenarios where you want to create
sundown/sunrise events in a one-time exception and in an exception.
5. If you clicked New Exception in step 4, the New Exception dialog opens. Follow these steps:
d. Enter the name, scope, dates, and recursions for the exception; click Close to return to the
Scheduler: Exception Schedules Web page; and then click Submit. See Creating Exception
Dates in the Exception Schedule for more information on how to create an exception and set
the range of dates and recursions for it in this dialog.

range of dates specified in step a. The Edit: <exception date > dialog opens.

the time the event is to occur. The Edit Events Of dialog opens. Alternatively, you can
right-click a time under the Time column or right-click the column to the right and click Add
