16. Setting the Time, Date, Location and Language
TouchPanel has a built-in clock and perpetual calendar that recognises leap years automatically. The clock and calendar
are used by the Scheduler to determine when to trigger scheduled events. The time and date can be displayed on a Screen
by adding a Clock control. To learn how to do this, see section 8.5.
16.1 Setting the Time Zone and Location
TouchPanel calculates local dawn and dusk times according to the selected time zone and location. This information
allows you to schedule events that are triggered at or around dawn or dusk.

current location,the more accurate the dawn and dusk time calculations will be.
12.
to save the changes.
Although TouchPanel calculates dawn and dusk times accurately, the location of your building will affect
actual dawn and dusk times. For example, if your building is in a valley then dawn may occur later and
dusk earlier than the dawn and dusk calculations predict.
Many websites provide longitude and latitude information. For example, you can find the approximate
longitude and latitude of your location at the Space Environment Center website: www.sec.noaa.gove/
Aurora/globeNE.html.
