Need a help in display of Date and time format in the incident form

[Thrupthi]

How to change the date format form 2018-07-20 07:37:35 to 20/07/2018 08:37:35.

I have created script include and client script for UTC end field. UTC end will display the GMT date and time automatically when we select the Incident End date and time. But here when I select the Incident date, UTC end date and time is displaying in different format. please can somebody help on how to display the date format in 20/07/2018 08:37:35.

Client Script:

var ga = new GlideAjax('PGIncidentAJAX');
ga.addParam('sysparm_name', 'getGMT');
ga.addParam('sysparm_date_time', newValue);
ga.getXML(processResponse);

function processResponse(response) {
var answer = response.responseXML.documentElement.getAttribute("answer");
g_form.setValue('u_utc_end', answer); 
}

Server Script:

var PGIncidentAJAX = Class.create();
PGIncidentAJAX.prototype = Object.extendsObject(AbstractAjaxProcessor, {

getGMT: function(){
var dt = this.getParameter('sysparm_date_time');
var gmt = new GlideDateTime();
// gmt.setStringParameter(dt.getByFormat("dd/MM/yyyy"));
gmt.setDisplayValue(dt);
return gmt;
},
type: 'PGIncidentAJAX'
});

I forgot to add var dt = this.getParameter('sysparm_date_time'); so make sure you have that before var gdt

var dt = this.getParameter('sysparm_date_time');
var gdt = new GlideDateTime();
gdt.setValue(dt.getDisplayValue());
var date = gdt.getValue().split(' ');
var dateonly = new GlideDate();
dateonly.setValue(date[0]);
var last = dateonly.getByFormat('dd/MM/yyyy') + " " + date[1];
return last;
