Periodic timers?

[mattias_mansson]

I know how to create a timer, but is it possible to create a periodic timer somehow? Or do you have to do a hack like starting a new one every time it expires?

You can make clock-based periodic rule triggers using cron e.g. every 5 minutes. Not a timer as such, as startup is not linked to any particular event.

Or you can make timers that call timers, allowing you to control when the sequence starts (and stops)

Design Pattern: Recursive Timers

Problem Statement Often one finds a situation where at the end of a triggered timer one wants to reschedule the timer to go off again. But if you do this in the normal way that means you need a full copy of the Timer’s body inside the Timer’s body inside the Timer’s body and so on and so on ad infinitum. This DP is deprecated. Please see Design Pattern: Looping Timers for the current best way to handle this type of problem.
