Timer can be described as the engine of the system, many task cannot run independently without Timer as trigger. There are two types of timer, one is 'Interval' which is fairly straightforward and the other type is 'Schedule'. The concept of entry for Schedule Timer is similar to cronjobs used in Unix/Linux environment, which is used to schedule commands to be executed periodically. Enter desired time of event into each time element. One or more figure can be entered into one column by using comma as separator. For instance, enter "0" into Second column will make a timer that trigger in every minute at 0th second. Another example is entering "0,30" into Second column will make a timer that trigger in every 30 second at both 0th and 30th second.

Tip

Regular used timers will be added by default upon creating new project.
