and my thingworx version is 9.3.0
try this..
let dateValue = new Date();
let calculatedDateValue = dateAddMinutes(dateValue, 480);
result = dateFormat(calculatedDateValue,"yyyy-MM-dd HH:mm:ss") ;

Hello,
You could try this since you are running thingworx 9.3.0:
let params = {
timezoneName: 'Asia/Hong_Kong' /* STRING */
};
let offset = Resources["TimezoneServices"].GetOffsetFromTimezone(params);
let offsethrs = offset / 100;
let DateTimeIn = new Date();
let datehrs = dateAddHours(DateTimeIn, offsethrs);
let isoFormat = dateFormatISO(datehrs);
This way you would get the timezone of Hong Kong, but if you lookup the tzdata list on wikipedia you can also find others.
Hope this helps.
Best regards.
Can you tell us the use case for the new Date()? On the server, TWx should be using UTC time. In the mashups, it gets converted to the local time on that clients machine. The dates that appear in the Composer services can be a bit confusing because of this. If you're looking to do date calculations in back-end services, you should be able to assume that ThingWorx will be using the UTC date. If you are creating dates to show on mashups, I would maybe suggest using the Expression functions where possible to create those as I find it less confusing (and you eliminate a back-end call to the server).
