Is a declaration defective because it does not show the date and place of execution?

In other cases dealing with the subject, a declaration defective because not showing the date and place of execution was held not to affect a judgment which had a sufficient basis in another declaration executed in full conformity with the statute (Hirschman v. Saxon, 246 Cal.App.2d 589, 593, 54 Cal.Rptr. 767); a declaration was held to show the place of execution when showing as a statement of venue, 'State of California, County of San Bernardino.' (McCauley v. Superior Court, 190 Cal.App.2d 562, 565, 12 Cal.Rptr. 119, 121. ⁴ )
