"[T]he court may extend the time fixed by any statute, rule or order for doing any act, upon such terms as may be just and upon good cause shown, whether the application for extension is made before or after the expiration of the time fixed." The grant of an extension is addressed to the sound discretion of the trial court. In exercising its discretion, the court may consider such factors as the length of the delay, the reason or excuse for the delay, and any prejudice to the party opposing the motion.
