Provided capabilities(1)

Attributes (5)

  • allow-execution If this node is allowed to execute timers. If this is false then the timers will be added to the database, and another node may execute them. Note that depending on your refresh interval if you add timers with a very short delay they will not be executed until another node refreshes.
