It depends upon the judge or magistrate... When I was a young officer in North Myrtle Beach SC, the procedure then was to assign our own court date on the citation. The rule was we had to be on duty for court and the date had to be at least 11 days from the citation issue date.
I assigned a date that was on the weekend. I realized the error, lined it out on the citation and inserted the correct date. The magistrate dismissed the citation, citing the court date error and correction as the reason.
Here in Miami-Dade, officers may amend the citation pretty much right up until the citation comes up for trial.
