请问各位大侠，这段显示时间的js怎么在ff下无法显示

var hours, minutes;
var intHours, intMinutes;
var today, theday;
today = new Date();
function initArray(){
this.length=initArray.arguments.length
for(var i=0;i<this.length;i++)
this[i+1]=initArray.arguments }
var d=new initArray(
"星期日",
"星期一",
"星期二",
"星期三",
"星期四",
"星期五",
"星期六");
theday = today.getYear()+"年" + [today.getMonth()+1]+"月" +today.getDate() + "日 " + d[today.getDay()+1]+" ";
intHours = today.getHours();
intMinutes = today.getMinutes();
if (intHours == 0) {
hours = "12:";
} else if (intHours < 12) {
hours = intHours+":";
} else if (intHours == 12) {
hours = "12:";
} else {
intHours = intHours
hours = intHours + ":";
}
if (intMinutes < 10) {
minutes = "0"+intMinutes;
} else {
minutes = intMinutes;
}
timeString = theday+hours+minutes;
document.write(timeString);

在某个浏览器是可以的，在ff下无法显示，
怎样改才能在ff有效显示？

没人知道吗？
