Defendant was charged with and convicted of unlawful delivery of a controlled substance, heroin, MCL 335.341(l)(a); MSA 18.1070(41)(l)(a), and sentenced to 1 year in prison. Defendant’s motion for a new trial, based on the same issues raised here, was denied on August 14, 1978. He appeals as of right, claiming (1) that the prosecutor failed to produce res gestae witnesses and (2) that a search warrant obtained and executed seven days after the delivery at issue was based on stale information.
Persons present at the scene of a crime are presumed to be res gestae witnesses able to testify regarding their observations.
People v Abdo,
In the case sub judice, although defendant most likely was aware of the several persons in his apartment at the time of the heroin delivery, he did not raise the production issue at trial. However, he did move for a new trial at the trial’s conclusion, properly perfecting the issue for appeal under the authority of Robinson, supra. Although *551 defendant complied with preservation procedure, we find on the merits that witness presentation was excused under an established exception to the production rule.
" 'Where the identity of the res gestae witness is made known to the defendant during or before trial and defendant does not move for endorsement or production of the witness [presentation is excused].’ ” People v Hernandez,84 Mich App 1 , 14;269 NW2d 322 (1978), quoting People v Buero,59 Mich App 670 , 674-675;229 NW2d 880 (1975).
Defendant presumably knew the identity of the persons in his apartment, but failed to disclose this information to the prosecution or move for the production of the witnesses during trial.

Hernandez, supra.
Whether this defendant actually delivered the heroin was never actually contested. Nor was there any question of identity. Any testimony that the witnesses could have given would not likely have affected the trial’s outcome. Therefore, we find that the prosecutor’s failure to produce was, at most, harmless and reversal on this basis is unnecessary. See
Hernandez, supra, People v Phillips,
Defendant further seeks reversal on the ground that the search warrant, obtained and executed seven days after the heroin delivery at issue, was based on stale information. There is authority for
*552
the quashing of a warrant based on outdated probable cause.
People v Siemieniec,
Assuming,
arguendo,
that a post-trial motion for a new trial effectively preserved defendant’s appellate rights on the search warrant issue, we conclude that the warrant was not stale. It is well-settled that probable cause supporting the search warrant must exist at the time of its issuance.
Sgro v United States,
"There is no hard and fast rule as to how much time may intervene between the obtaining of the facts and the making of the affidavit upon which the search warrant is based” People v Mushlock,226 Mich 600 ;198 NW 203 (1924).
Certainly the passage of time is a consideration in judging a search warrant’s vitality. See
People v Willis,
In the instant case, the record reveals that the first delivery on January 10, 1978, which forms the basis of defendant’s conviction, was not an isolated occurrence. There was a second delivery on January 16, 1978, attested to in the affidavit accompanying the search warrant and in testimony at trial. Thus, although there were seven days between the original information and the search warrant of January 17th, there was corroborative information obtained just 24 hours before the warrant’s issuance. We cannot then say that the search warrant was stale.
We conclude that both of defendant’s arguments on appeal are without merit. Accordingly, his conviction is affirmed.
Notes
In cases like the present, where only the defendant is aware of the witnesses’ identity, we are persuaded that the prosecutor is excused from endorsement and production by
