(a)    Computation. Computation of time shall be governed by Florida Rule of General Practice and Judicial Administration, except for rule 8.655, to which 2.514(a)(2)(C) shall not apply and the statutory time period shall govern.

(b)    Enlargement of Time. When by these rules, by a notice given thereunder, or by order of court an act is required or allowed to be done at or within a specified time, the court for good cause shown may, at any time in its discretion, (1) with or without notice order the period enlarged if the request is made before the expiration of the period originally prescribed or as extended by a previous order, or (2) upon motion made and notice after the expiration of the specified period permit the act to be done where the failure to act was the result of excusable neglect; but it may not, except as provided by law or elsewhere in these rules, extend the time for making motion for new trial, for rehearing, or for vacation of judgment or for taking an appeal. This rule shall not be construed to apply to detention or shelter hearings.

(c)    Time for Service of Motions and Notice of Hearing. A copy of any written motion which may not be heard ex parte and a copy of the notice of the hearing thereof shall be served a reasonable time before the time specified for the hearing.
