Restricting past date and time in date/time field using onChange client script

[fgh1]

Restricting past date and time in date/time field using on change client script as below, but it is restricting only old date IF I am selecting past time of todays date it is not restricting, it so it should restrict past time too

my onChange client script for DateTime field -

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }
    var EventDateTime = newValue;
    var newdt = new Date(EventDateTime);
    var EventDate = formatDate(newdt, 'yyyyMMdd');
    var RightNow = new Date();
    var RightNowDate = formatDate(RightNow, 'yyyyMMdd');
    if (EventDate < RightNowDate) {
        g_form.clearValue('end_date');
        g_form.showFieldMsg('end_date', 'Planned end date must be after the current date', 'error', true);    }}

@Ankur Bawiskar please assist

update as this

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
	if (isLoading || newValue === '') {
		return;
	}
	g_form.hideErrorBox('end_date');
	if (newValue != oldValue) {
		var RightNow = new Date().getTime();
		var end = new Date(g_form.getValue('end_date')).getTime();
		if (end < RightNow) {
			g_form.clearValue('end_date');
			g_form.showFieldMsg('end_date', 'Planned end date must be after the current date', 'error', true);
		}
	}
}

Hello @Ankur Bawiskar 

I have tried your code but it is restricting future time as well as past time for todays date 

I have added logs to debug I am getting End time lesser than Rightnow time  whether I am selecting past time or future time for todays date so it is restricting future time as well as past time for todays date .
