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

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'
});

The important thing to remember about ServiceNow is that internally, all dates and times are stored as UTC. It's only when it displays it to a human in a field that the timezone is applied (or in a script if you use getDisplayValue()). 

Similarly, if you use setDisplayValue() it is stripping off the timezone to save a UTC value. If you do something like this, you are introducing a timezone offset issue and either losing or gaining time.

var gdt = new GlideDateTime(); //current time/date object in UTC
current.start_time = gdt.getDisplayValue(); // WRONG! getDisplayValue() has a TZ applied,
                                            // start_time is a UTC value -
                                            // you've just made an offset error

Similarly,

var gdt = new GlideDateTime();
current.start_time.setDisplayValue(gdt.getValue()); // WRONG!!!

You're getting a UTC value from gdt and then telling start_time "here comes a value with a timezone, be sure to strip off the system time zone when you save it".

Proper example:

var gdt = new GlideDateTime();
current.start_time = gdt.getValue();

or

var gdt = new GlideDateTime();
current.start_time.setDisplayValue(gdt.getDisplayValue());

See how they match? 🙂

It is working all i need is the format to be changed

getGMT: function(){

                        var dt = this.getParameter('sysparm_date_time');

                var gdt = new GlideDateTime();

                gdt.setDisplayvalue(dt.getDisplayValue());

                        return gdt;

            },

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

you can do

var longDateTime = gdt.getByFormat('dd/MM/yyyy hh:mm:ss');
	return longDateTime;

Mike that is not displaying any date on load, can you please help me more with script part, my scripting knowledge is not good so please

[Mike Patel]

Only way I can think of is to split and return

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;
