Try:

gs.info(dt);
var iso = new Date(dt.getNumericValue());
gs.info(iso.toISOString());

An example to convert DateTime field to ISO date/time.

Client Script

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '' || oldValue == newValue) {
        return;
    }

    var ajax = new GlideAjax('DateTimeUtil3');
    ajax.addParam('sysparm_name', 'getISOTime');
    ajax.addParam('sysparm_datetime', newValue);
    ajax.getXMLAnswer(function(answer) {
        if (answer.length > 0) {
            g_form.showFieldMsg("datetimefield", answer);
        }
    });
}

Script Include:

var DateTimeUtil3 = Class.create();
DateTimeUtil3.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    getISOTime: function() {
        var dt = this.getParameter('sysparm_datetime');
        var gdt = new GlideDateTime(dt);
        var isoDt = new Date(gdt.getNumericValue());
        return isoDt.toISOString();
    },
    type: 'DateTimeUtil3'
});

Result:
