The main difference between a retentive and nonretentive timer is that a retentive timer maintains the current time even when power is removed from the device or when the timer rung goes false. Nonretentive timers do not maintain the current time in these situations. The programming capabilities for time delay periods are not necessarily different between the two types of timers.
