Control and Combine Html Form fields before submitting

Question

I have a html form with date and time fields separately, when user clicks on save button I want to combine both date and time into date field and submit only date field with combined date and time. I already have "skip_element" attribute which I can use to avoid submitting of any field by setting true or false. My major requirement is I want to combine the date and time field values into one field and submit the form. I have backbone syphone to serialize the form. Can I do something there to combine the date and time field values and removing the time field?

Otherwise, I need to do manual coding in javascript function to combine these two fields and removing the time field from my array before sending dates with times to server. And I have to do it in many pages of my application. If it can be achieved in simple way that would be great.

You will probably need something like this.

function passDateAndTime () {
  var date = '05/10/2015';
  var time = '05:00:00 AM'; //the time wil need to be a date object, The time field will probably yield the correct time format.
  var date_time = joinDateAndTime_(date, time);
  Logger.log('date and time: ' + date_time);

  }

function joinDateAndTime_(date, time) {
  var date = new Date(date); Logger.log('date: ' + date);
  date.setHours(time.getHours());
  date.setMinutes(time.getMinutes());
  return date;
}
