The Timer Editor

The Schedule panel

• Scheduling type defines if the functions need to be recalculated at fixed rate or fixed delay. This is because the function execution can take a certain time.
  For example suppose the rate at which the timer ticks is 15 seconds and that the function execution takes10 seconds. If you choose fixed rate the timer will tick every 15 seconds, independently by the function execution time. If instead you choose fixed delay the timer will wait 15 seconds to tick after the end of each function execution.
  So choosing fixed rate the functions will fire with the pattern 0, 15, 30, 60 ...
  Instead choosing fixed delay the functions fill fire with the pattern 0, 25 (10+15), 50 (25+10+15), 75 (50+10+15)...
• Time unit defines the time unit used for the timer. The timer can tick every N seconds, hours or days.
• Initial delay defines the seconds to wait from the moment the timer has been loaded (because the timer has been added to the project or the project containing the timer has been loaded) to the moment it will tick the first time.
• Delay/period is the N that we mentioned when defining the timer's time unit. It is the number of units to wait between two ticks of the timer (number of seconds, hours or days).
• Excluded periods/days defines a list of periods in which the timer does not tick. To add a new period to the list click on the Add button, to remove a period from the list select it and click on the Remove button (you will need to confirm), to update a period in the list click on the Update button.
  Clicking on the Add button you open the exclusion dialog. with which you can add exclusion periods. Clicking on the Update button the exclusion dialog appears, with the content of the selected exclusion period.
