The Timespan section allows for four periods of time to be defined. The be-
ginning and end of the time periods will trigger actions in the show control
page.
An advantage of Timespans over normal scheduler actions is that Timespans are
power-cycle safe. When the QuadCore is without power during the moment of
a normal scheduler trigger then it will miss that trigger. Timespans, however,
will still receive the trigger once the power is restored after the moment has
occurred.
Timespans are ideal for defining periods of time during a year (like Christmas
or Easter) or periods during the day (like opening times).
When entering the date and time data, XX's can be used to signify a 'don't
care'. This allows for easily programming of yearly, monthly or daily re-occuring
events.
