Set default time in Date/Time field on catalog

[S_53]

I have a date/time variable on a catalog request. I need to set the time default to 20:00:00 when a date is picked and user can update the time if wanted. I tried below script where it is setting the time to 20:00:00 but users are not able to override it. Time is getting locked.

Any thoughts? 

Catalog Client Script - OnChange of date/time field

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
g_form.setValue('AppOps_Requested_by_date', newValue.replace(/[0-2][0-9]:[0-5][0-9]:[0-5][0-9]$/,"20:00:00"));

//Type appropriate comment here, and begin script below
}

So are you trying to make it so as soon as the click on the calendar picker it defaults the time to 20:00:00.

Try this it worked for me.

function onChange(control, oldValue, newValue, isLoading) {
	if (isLoading || newValue == '') {
		return;
	}
	
	//Type appropriate comment here, and begin script below
	var dt = newValue.toString().split(' ');
	g_form.setValue('AppOps_requested_by_date', dt[0] + ' 20:00:00');
}

Not sure if I am missing something here.

My updated Script as suggested: 

It is setting the current time:

You have to have a space before the 2 (" 20:00:00").
