The embodiment of the invention provides a processing method and device of a timer. The processing method of the timer comprises the steps that the predetermine generating time of each task in a system is obtained; the predetermine generating time of each task corresponds to one first node; according to the sequence of the predetermine generating times of the first node, the first nodes form at least two layers of task queues with skip list structures. The processing method of the timer is quick to operate.
