When you say that you "have a javascript date", do you mean that your
structure contains a javascript date object?  If so, it is very easy to do what
it is you are asking.

- Method #1
  Use the DateObj methods to set the Hour, Minute, and Second attributes:

  Given the time string in some variable, e.g., myTime = '01:23:45'

  var timeFields   = myTime.split( ':' )
  var myDateObj = new Date()
  myDateObj.setHour( parseInt( timeFields[ 0 ], 10 ) )
  myDateObj.setMinutes( parseInt( timeFields[ 1 ], 10 ) )
  myDateObj.setSeconds( parseInt( timeFields[ 2 ], 10 ) )

- Method #2
  Let the Date object handle things for you;

  Given some date object (e.g., "myDateOjb")

  var myDateObj = new Date()

  We can format the date portion as a string:

  function DateAsStr( when ) {
    function D2( val ) {
      return ( val < 10 ) ? '0' + val : val
    }
    return D2( when.getMonth() + 1 ) + '/' + D2( when.getDate() ) + '/' + when.getFullYear()
  }

  var myDateStr = DateAsStr( myDateObj )

  Then, we can append the timestamp portion to this string, and let the
  Date Object constructor handle it.

  var newDateObj( DateAsStr( myDateObj ) + ' ' + myTimeStr )

Yep.
var time = "01:22:54";
 
var date = new Date();
 
var strs = time.split(":");
 
date.setHours(strs[0]);
date.setMinutes(strs[1]);
date.setSeconds(strs[2]);
 
alert(date);
