Issue in calculating time difference in different timezone

[kun1]

Hi Team,

My system timezone is in EST and servicenow timezone is in  IST. Below are the script which calculate time difference but its not working properly.

Catalog Client Script:-

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading)

    {

        return;

    }

    //start the validation for star date time.

    if (newValue != '')

    {

        var ga = new GlideAjax('BIIB_CPGResizeConfirmDate');

        ga.addParam('sysparm_name', 'chkstartstopDate');

        ga.addParam('sysparm_time', g_form.getValue('planned_start_date_time'));

        ga.getXML(NewParse);

    }

    function NewParse(response) {

        var answer = response.responseXML.documentElement.getAttribute("answer");

        if (answer == 'false') {

            alert("Please select a future date");

            g_form.setValue('planned_start_date_time', '');

        }

    }

}

Script include:-

var BIIB_CPGResizeConfirmDate = Class.create();
BIIB_CPGResizeConfirmDate.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    chkCurrDate: function() {//Check if given Date time is in past or not.
        var ActualEndDate = this.getParameter('sysparm_time');
        var dif = gs.dateDiff(gs.nowDateTime(), ActualEndDate, true);
        if (dif < 1800) {
            return false;
        } else {
            return true;
        }
    },
    chkstartstopDate: function() {//Check if given Date time is in past or not for start stop.
        var ActualEndDate = this.getParameter('sysparm_time');
        var dif = gs.dateDiff(gs.nowDateTime(), ActualEndDate, true);
        if (dif < -2) {
            return false;
        } else {
            return true;
        }
    },
    
});

it will not calculating time diff properly when system(EST) and servicenow (IST) timezone is diff

Hi,

why not use UI policy and no scripting will be required?

Something like this; it's just an example. Please enhance it

Start Time [After] Today

function onCondition() {

	// valid
	alert('Start date cannot be in future');
	g_form.showErrorBox('start_date_time','Invalid');
	g_form.setMandatory('start_date_time', true);

}

Regards
Ankur
