Computer system, carrier medium and method for adjusting an expiration period

A system, carrier medium and method for adjusting an expiration period are provided herein. In one embodiment, the system includes a timing logic unit coupled to produce a predetermined number of pulses in response to a transaction request transmitted from a source device to a target device coupled within or external to the system. In general, the timing logic unit is configured to generate a time expired signal upon producing a last one of the predetermined number of pulses. The system may also include a processor for executing program instructions configured to programmably alter a rate at which the predetermined number of pulses are produced by the timing logic unit. In this manner, the system is configured to adjust an expiration period for completing a transaction cycle associated with the transaction request.
