var date = new Date ();
var seperator1 = "-";
var Seperator2 = ":";
var month = Date.getmonth () + 1;
var strdate = Date.getdate ();
if (month >= 1 && month <= 9) {
month = "0" + month;
}
if (strdate >= 0 && strdate <= 9) {
Strdate = "0" + strdate;
}
var currentdate = date.getfullyear () + seperator1 + month + Seperator1 + strdate
+ "" + date.gethours () + Seperator2 + date.getminutes ()
+ Seperator2 + date.getseconds ();
return currentdate;
