GlideDate and GlideDateTime.getLocalDate() are not equivalent, why?

Hi everyone, I am new to ServiceNow and currently doing the developer fundamantels.

https://developer.servicenow.com/dev.do#!/learn/learning-plans/quebec/new_to_servicenow/app_store_le...

there is a challenge to prevent users from submitting same date requests.

This works:

(function executeRule(current, previous /*null when async*/ ) {

	var rightnow = new GlideDateTime();
    var today = rightnow.getLocalDate();
    var whenNeeded = new GlideDateTime(current.u_when_needed);
	var isToday = whenNeeded.getLocalDate();

    if (isToday.compareTo(today) == 0) {
        gs.addErrorMessage("You cannot submit NeedIt requests for today.");
		current.setAbortAction(true);
    }
 
})(current, previous);

whereas this does not:

(function executeRule(current, previous /*null when async*/ ) {

	var today = new GlideDate();
    
    var whenNeeded = new GlideDateTime(current.u_when_needed);
	var isToday = whenNeeded.getLocalDate();

    if (isToday.compareTo(today) == 0) {
        gs.addErrorMessage("You cannot submit NeedIt requests for today.");
		current.setAbortAction(true);
    }
 
})(current, previous);

I expected both of these to work, since getLocalDate() should return a GlideDate Object. as in the API: https://developer.servicenow.com/dev.do#!/reference/api/quebec/server/no-namespace/c_APIRef#r_Scoped...

Hi,

the compareTo() function works on GlideDateTime and not on GlideDate object

So you better use the 1st option

Hi,

The compareTo function works for either GlideDate or GlideDateTime, but they must be of the same type.

var date1 = new GlideDate();
var date2 = new GlideDate();
gs.info(date1.compareTo(date2));
//works

var date11 = new GlideDateTime();
var date22 = new GlideDateTime();
gs.info(date11.compareTo(date22));
//works

var date111 = new GlideDateTime();
date111 = date111.getLocalDate();
var date222 = new GlideDate();
gs.info(date111.compareTo(date222));
//doesn't work

Please mark reply as Helpful/Correct, if applicable. Thanks!
