Var hour = now. getHours ();
Var minu = now. getMinutes ();
Var sec = now. getSeconds ();
Var week;
Month = month + 1;
If (month <10) month = "0" + month;
If (date <10) date = "0" + date;
If (hour <10) hour = "0" + hour;
If (minu <10) minu = "0" + minu;
If (sec <10) sec = "0" + sec;
Var arr_week = new Array ("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday ");
Week = arr_week [day];
Var time = "";
Time = year + "year" + month + "month" + date + "day" + week + "" + hour + ";" + minu + ";" + sec;
If (document. all)
{
Bgclock. innerHTML = "[" + time + "]"
