When I send a date through JSON from Java to Javascript, it sends something like this:
var ds = "11:07:47 13/01/2011"; Javascript fails to parse this string into date
var d = new Date(ds); Any ideas?

You need some JS that parse the String and return the year, month, day, minute,hour, second in strings:
var hour = ds.split(":")[0], minute = ds.split(":")[1], last_part = ds.split(":")[2], second = second_part.split(" ")[0], last_part2 = second_part.split(" ")[1], day = last_part2.split("/")[0], month = last_part2.split("/")[1], year = last_part2.split("/")[2]; and then instantiate the Date constructor:
var d = new Date ( year, month, day, hour, minute, second );

Line 3 should be
second = ds.split(":")[2],, delete 4th line, 5th line should be last_part2 = ds.split(" ")[1],. You could rename last_part2 as it isn't the 2nd one anymore.

thanks for writing the code , it worked like a charm!

An alternate approach would be to use
moment.js to get a Date object: var d = moment(ds, "HH:mm:ss DD/MM/YYYY").asDate(); The second string is the format to use for parsing the input date String.To be on the safe side you should get the time in milliseconds in Java and send that through JSON to JavaScript. There you can use
var d = new Date(); d.setTime(valueInMilliseconds);

There are a number of ways you can call the Date constructor.
From the reference at http://www.w3schools.com/js/js_obj_date.asp:
new Date() // current date and time new Date(milliseconds) //milliseconds since 1970/01/01 new Date(dateString) new Date(year, month, day, hours, minutes, seconds, milliseconds)

function stringToDate(_date,_format,_delimiter) { var formatLowerCase=_format.toLowerCase(); var formatItems=formatLowerCase.split(_delimiter); var dateItems=_date.split(_delimiter); var monthIndex=formatItems.indexOf("mm"); var dayIndex=formatItems.indexOf("dd"); var yearIndex=formatItems.indexOf("yyyy"); var month=parseInt(dateItems[monthIndex]); month-=1; var formatedDate = new Date(dateItems[yearIndex],month,dateItems[dayIndex]); return formatedDate; } stringToDate("17/9/2014","dd/MM/yyyy","/"); stringToDate("9/17/2014","mm/dd/yyyy","/") stringToDate("9-17-2014","mm-dd-yyyy","-")
