A retentive timer, as its name suggests, retains the current time even if power is removed from the device or when the timer rung goes false. Nonretentive timers, on the other hand, reset to zero once power is removed or when the timer rung goes false. The length of time delay periods that can be programmed is not affected by whether the timer is retentive or nonretentive.
