OPINION
By the Court,
The facts pertinent to this appeal are briefly as follows:
On August 1, 1946, a decree was made and entered in the Eighth Judicial District Court of the State of Nevada, in and for the County of Clark, in the above-entitled action, granting to plaintiff an absolute divorce, awarding to her the custody of the minor child the issue of the marriage, ordering that defendant pay plaintiff a certain monthly sum for the support and maintenance of the child, and finally, approving a property agreement *115theretofore made by the parties which had been admitted into evidence. The matter was tried by the court without a jury, and upon the complaint of plaintiff and the answer of defendant.
On January 6, 1947, the plaintiff noticed a motion to amend the decree of divorce entered August 1, 1946, for the 13th day of January, 1947. Plaintiff gave notice that she would move the court to amend the decree by having the court adopt as a part of the decree the provisions of the property agreement, and further, that she would move the court that the amended decree be entered nunc pro tunc as of August 1, 1946. The defendant in writing acknowledged service of the notice, consented to the hearing of the motion on January 6, 1947, waived time for notice and consented to the amendment of the decree as set out in plaintiff’s motion, using this language: “Consents to the amendment of said decree of divorce as applied for by plaintiff under and by virtue of the afore-mentioned notice of motion to amend the decree of divorce.” Thereupon, the court on the same day made its order granting leave to amend and on the same day made and entered its “Amended Decree of Divorce” reciting in words the provision of the property agreement as its decree in respect to the maintenance and support of plaintiff and the property rights and relations of the parties, ordering the parties to carry such provisions and ordering that the amended decree be entered nunc pro tunc as of August 1, 1946. The original decree of August 1, 1946, had provided “It is further ordered, adjudged and decreed that the property settlement agreement entered into between plaintiff and defendant on the 4th day of May, 1946, be, and the same is, hereby approved.” The amended decree of January 6, 1947, repeated said order and added, among other things, the following:
“It is further ordered, adjudged and decreed that defendant pay plaintiff until her remarriage, as and for *116her support and maintenance, the sum of $1350 per month commencing on August 4, 1946, and thereafter on the 4th day of each month until and including April 4, 1947; and, thereafter on the 4th day of each month commencing May 4, 1947, that defendant pay plaintiff as and for her support and maintenance, a sum equivalent to 36% of his monthly earnings, provided, however, that the monthly payments commencing May 4, 1947, shall not exceed the sum of $1350 or be less than the sum of $450; that at the end of each year during the term of the aforesaid agreement, defendant shall deliver to the plaintiff a statement of his earnings during the preceding year, said statement to be certified to be correct.”
On March 26, 1947, the defendant filed in the action a motion and notice of ¿notion, wherein notice was given that the defendant would on the 4th day of April, 1947, move the court to modify the decree of August 1, 1946, and January 6, 1947, in certain particulars. The plaintiff was served and appeared specially, after substitution of attorneys, for the purpose of contesting the jurisdiction of the court to hear and determine the motion noticed by the defendant. The matter was heard on the point presented by plaintiff and the question was resolved in favor of the defendant by the court. The plaintiff did not contest the matter on its merits and the court ruled in favor of the defendant on the motion and entered the decree denominated “Modified Decree of Divorce” modifying the decree of January 6, 1947, as above set forth. Plaintiff has appealed and assigns error in the order overruling her objection taken to the court’s assuming jurisdiction of the motion. Plaintiff in the court below, who is appellant here, will be hereinafter referred to as plaintiff and the respondent husband as defendant.
Briefly, the argument of counsel for plaintiff has been that as the decree made January 6, 1947, was entered *117nunc pro tunc as of August 1, 1946, the same was retrospective in all respects; that by virtue of Rule XLV of District Courts and Public Act No. 56 (being Chapter 162, Public Laws of Nevada, 1947, Page 531) the district court no longer had jurisdiction since more than six months had elapsed between August 1, 1946, and the date on which the last motion was noticed. Plaintiff argues further that if her contention should prevail this case does not come under the principal enunciated by this court in Aseltine v. District Court, 57 Nev. 269, 62 P.2d 701, as in that case there was held to be an implied reservation of jurisdiction which does not appear here.
The defendant argues that conceding that a nunc pro tunc order is retrospective as to the substantive rights of the parties it is not as to third persons or as to the procedural rights of the parties to the action, and, finally, that if the court rules that the decree made and entered on January 6, 1947, is retrospective in all respects the ease comes under the principle announced in Aseltine v. District Court.
It will not be necessary to enlarge on the facts stated above by a discussion of the various decrees for the purpose of deciding whether this case comes under the principle of the Aseltine case. It has been concluded that the matter should be decided on the first point raised by counsel, that is to say, whether the order made January 6, 1947, that the decree amending the decree of August 1, 1946, be entered nunc pro tunc operates to cut off defendant’s rights to move to modify the decree of January 6, 1947.
It should be pointed out here that the decree of January 6, 1947, enlarged upon the original in at least two respects: By adopting in words the provisions of the property agreement as the decree of the court the court gave to plaintiff in addition to her contractual rights then existing the right to invoke contempt proceedings *118in this state and the rights of a judgment creditor in this or any other state. Nor could defendant have moved to modify the decree in respect to the provisions made for the plaintiff before the decree entered on January. 6, as there was nothing on which the court could have acted.
The record in this case has been very carefully examined with a view to finding anything therein which would sustain the entry of the order nunc pro tunc. The minutes of the court, the transcript, the original decree and the order granting leave to amend do not support a finding that the court in amending the decree acted to have the record speak the truth as to what occurred on August 1, 1946. It appears that the motion made by plaintiff on January 6, 1946, was upon the pleadings and records on file and on that date the minutes of the court, testimony of plaintiff and the order of the court show that all that plaintiff requested or received was approval by the court of the agreement made by the parties. Nor in fact was the motion made to have the record speak the truth as to what occurred on August 1, 1946, but a motion to amend the decree and have the decree as amended entered nunc pro tunc as of August 1, 1946.
The object and purpose of a nunc pro tunc order is to make a record speak the truth concerning acts done. Talbot v. Mack, 41 Nev. 245, 255, 169 P. 25. The court there intimated, and in this is supported by authority, that an order nunc pro tunc cannot be made use of nor resorted to, to supply omitted action. Power to order the entry of judgment nunc pro tunc cannot be used for the purpose of correcting judicial errors or omissions of the court. Nor can this procedure be employed to change the judgment actually rendered to one which the court neither rendered nor intended to render. Wright v. Curry, 208 Ark. 816, 187 S.W.2d 880; Schroeder v. Superior Court, 73 Cal.App. at 687, 239 P. 65.
And so it was held in Barkelew v. Barkelew, 73 Cal. *119App.2d 76, 166 P.2d 57, that an interlocutory divorce decree would not be amended nunc pro tunc on the theory of correcting a clerical error so as to limit the defendant’s obligation to make one hundred twenty-five dollar monthly payment’s for the wife’s support to those months when the wife’s income from outside sources was less than one hundred and fifty dollars per month, where in fact the amendment would change and enlarge the judgment rather than make the judgment conform to the decision actually rendered; although it was recognized there that a clerical error in a judgment appearing on the face of the record may be corrected by nunc pro tunc order and such correction made at any time. It was also pointed out that a nunc pro tunc order correcting a clerical error in a judgment is to make the judgment as entered conform to the judicial decision actually made.
It was pointed out in State v. District Court of the Fifth Judicial District, 110 Mont. 36, 98 P.2d 883, that the test of whether a judgment may be amended nunc pro tunc is whether the change will make the record speak the truth as to what was actually determined or. done or intended to be determined or done by the court or whether it will alter such action or intended action.
A nunc pro tunc order cannot be used to enlarge the judgment as originally rendered, and a judgment varying the rights of the parties as fixed by the original decision is void although the court informed counsel of his decision to do so and no objection was made. See Felton Chemical Company v. Superior Court, 33 Cal.App., 2d 622, 92 P.2d 684. For further authorities on the function or office of a nunc pro tunc order, see Words and Phrases, Vol. 28, commencing at page 983. The court may amend to correct mere clerical errors or omissions at any time and has inherent power to do so. See Silva v. District Court, 57 Nev. 468, 66 P.2d 422, and Annotation in 126 A.L.R. 956. But this power should be distinguished from the power to amend so as to *120enlarge or in any manner substantially alter the rights of the parties under the original order for the first time upon application of the parties to the action.
This raises the question as to whether the parties by their consent could give the court jurisdiction or power to do something which it could not have done without such consent. While the court has an inherent power to make the record speak the truth as to what was actually done (Lindsay v. Lindsay, 52 Nev. 26, 280 P. 95, 67 A.L.R. 824) and the court may in its discretion rely on its memory as to what was actually done and may refresh its memory from any source it deems reliable (Gottwals v. Rencher, 60 Nev. 35, 47, 56, 92 P.2d 1000, 98 P.2d 481, 126 A.L.R. 1262), nevertheless, the court would not have power to modify its decree so as to affect the substantial rights of the parties as they existed under the original order and make such an entry nunc pro tunc. It is my conclusion that the consent of the parties that the amended decree be entered nunc pro tunc could not give the court jurisdiction to do so. The power to make such an order and have it entered nunc pro tunc depends on something having actually happened which was not recorded. The consent of the parties cannot confer jurisdiction. Jasper v. Jewkes, 50 Nev. 153, 254 P. 698. This principle has been maintained in this court since the case of Hastings & Company v. Berning Moscow Company, 2 Nev. 93, where it was held: “When a defendant consents to a judgment against himself he must be held to admit every possible fact consistent with the pleadings which would be necessary to support the judgment. It may also be held that by consent he waives all errors. But no defendant can by consent confer power or jurisdiction on a Court to enter an illegal judgment or judgment beyond the jurisdiction of the Court.” And it was held in Maitia v. Allied L. & L. Company, 49 Nev. 451, 248 P. 893, that a jurisdictional requirement cannot be waived. A court cannot be governed by a stipulation *121as to the legal effect of a judgment. People v. Traeger, 339 Ill. 356, 171 N.E. 548. Where in fact there is no basis for such an entry consent will not give the court jurisdiction to do so. Owen v. Owen, 157 Va. 580, 162 S.E. 46. Nor can consent of the parties restore original jurisdiction if in fact the court has lost the same. Donner v. Superior Court, 82 Cal.App. 165, 255 P. 272.
It will not be necessary under such a ruling to discuss the question raised by the defendant as to whether an order made nunc pro tunc operates to cut off the procedural rights of the parties. For a case on this point see Tresemer v. Gugle, 70 Ohio App. 409, 42 N.E.2d 712. It is sufficient to hold that the order of the court that the amended decree of January 6, 1947, be entered nunc pro tunc as of August 1, 1946, was void as an improper exercise of power or jurisdiction to enter orders nunc pro tunc. There remains only the necessity of fixing the rights and obligations of the parties as they now exist under the record.
It does not follow that if the court was without power to order that the decree be entered nunc pro tunc, it was without jurisdiction to act upon plaintiff’s motion on January 6, 1947. The proposition amounts simply to this: That the court had jurisdiction to entertain, by virtue of District Court Rule XLV, then controlling in such matters, the motion to amend but it did not have jurisdiction, nor could the parties by consent confer jurisdiction, to the entering of the amended decree nunc pro tunc.
By virtue of District Court Rule XLV a definite time limit is fixed within which judgments may be vacated or substantially altered unless the matter is controlled by some other circumstance. Lauer v. District Court, 62 Nev. 78, 140 P.2d 953; Lindsay v. Lindsay, 52 Nev. 26, 280 P. 95, 67 A.L.R. 824; Crowell v. Second Judicial District Court, 54 Nev. 400, 19 P.2d 635.
“Court rules when not inconsistent with the constitution or laws of the state have the effect of statutes.” *122Lightle v. Ivancovich, 10 Nev. 41; Haley v. Eureka County Bank, 20 Nev. 410, 22 P. 1098.
April 10, 1948.
August 6, 1948.
196 P.2d 766.
Rule XLY provides: “No judgment, order or other judicial act or proceeding, shall be vacated, amended, modified, or corrected by the court or judge rendering, making, or ordering the same, unless the parties desiring such vacation, amendment, modification, or correction shall give notice to the adverse party of a motion therefor, within six months after such judgment was rendered, order made, or action or proceeding taken.” Accordingly the court on January 6, 1947, had jurisdiction to entertain plaintiff’s motion. This rule still governed these matters on March 26 when the last motion was filed in this matter, as Public Act No. 56 (Nev. Stats. 1947, Chap. 162, p. 531) was not approved until March 27, 1947.
Accordingly, it is ordered that the modified decree of divorce made and entered on the 3d day of May 1947, by the district court be and the same is hereby affirmed. Each party shall pay his and her own respective costs on appeal.
