setInterval循环次数问题

Question

setInterval(function () {
var date = new Date();
var hour = date.getHours();
var minute = date.getMinutes();
var second = date.getSeconds();
if (hour == time1 && minute == time2 && second == time3) {
window.frame1.location.href = path;
return false;
}
}, 500);

                            这是时间刚好就运行一次，如何做到时间刚好就运行指定次数？
