I am trying to pick up value from datetimepicker tetxbox and compare those values with current time.

JSFiddle

        //startTime textbox text = 19/12/2014 03:58 PM

        var startTime = Date.parse($('[id$=txtStartDate]').val().toString());



        //endTime textbox text = 19/12/2014 04:58 PM

        var endTime = Date.parse($('[id$=txtEndDate]').val().toString());



        var currentTime = Date.now();

        alert(startTime);

        alert(endTime);

        alert(currentTime);



        if (currentTime >= startTime && currentTime <= endTime) {

              alert();



        }

Date.parse() is used fro converting string to milliseconds since Jan 1 1970.
Date.now() returns current date milliseconds since Jan 1 1970.

But the above conversion methods are not working properly.
What should be logic to compare datetime by first sonverting string in format like 19/12/2014 03:58 PM to Date object and then do comparing.
