What is the relevant time period for a motion alleging that a defendant was denied a speedy trial by the Court of Appeal?

Defendant contends that the delay in starting his trial denied him the speedy trial guaranteed by the Sixth Amendment. The relevant time period is the interval between the time of accusation, in this case the indictment, and the trial. United States v. Valentine, 783 F.2d 1413, 1417 (9th Cir.1986). Defendant was indicted on July 27, 1988, and the trial commenced on January 10, 1989, an interval of about six months. A sixth month delay is a "borderline case" sufficient to trigger an inquiry into the other factors defined in Valentine. Id.; U.S. v. Simmons, 536 F.2d 827, 831 (9th Cir.), cert. denied, 429 U.S. 854 (1976).
