You need to format the date at first. Better use moment.js for date manipulation — mohamedrias

this too will not work in FF. This alerts invalid date.

Correct it will not work in FF. Have a look at this code.

var dateString = '02-APR-2015 11:08 AM';
var d = dateString.split(" ");
dArray = d[0].split("-");
var day = dArray[0];
var month = dArray[1];
switch(dArray[1]) {
    case "JAN" :
        month = "01";
        break;
    case "FEB" :
        month = "02";
        break;
    case "MAR" :
        month = "03";
        break;
    case "APR" :
        month = "04";
        break;
    case "MAY" :
        month = "05";
        break;
    case "JUN" :
        month = "06";
        break;
    case "JUL" :
        month = "07";
        break;
    case "AUG" :
        month = "08";
        break;
    case "SEP" :
        month = "09";
        break;
    case "OCT" :
        month = "10";
        break;
    case "NOV" :
        month = "11";
        break;
    case "DEC" :
        month = "12";
        break;
    default :
        month = "01";
        break;        
}
var year = dArray[2];
var tm = d[1].split(":");
    if(d[2] == "AM") {
        var tm_h = tm[0];
   } else {
       var tm_h = tm[1]+12;
   }
   var tm_m = tm[1];
       var newStr = year+"-"+month+"-"+day+"T"+tm_h+":"+tm_m+":"+"00";

var date = new Date(newStr);
alert(date);

Use this instead :

date = new Date('02-APR-15 11:08 AM');
alert(date);

Date.parse returns a timestamp which is an integer when a valid date string is supplied, otherwise NaN. So you need to convert your date string to a valid string like:

var s = '02-APR-15 11:08 AM'.replace(/(\d{1,2})-(\w+)-(\d{2})/, '$2 $1 20$3')
date = new Date(s);
