http://legal-dictionary.thefreedictionary.com/enter+a+judgment
enter a judgment v. to officially record a judgment on the "judgment roll," which entry is normally performed by the court clerk once the exact wording of the judgment has been approved and signed by the trial judge. All times for appeal and other post-judgment actions are based on the date of the entry of judgment and not the date when the judgment is announced.
So the date of "entry of judgement", the date of judgement approval, and the date when the judgement is announced can be all different? The date of "entry of judgement" is the date that really matters the legal status?
