Timer Does Not Work Correctly in Different Time Zones

[bezbee]

Hi,

Thanks for helping me!

My goal was to make an announcement on Feb, 3 at 9 am NYC time on http://c0784.paas2.tx.modxcloud.com/

Here is how the timer configurated:
$(function(){
$("#future_date").countdowntimer({
dateAndTime: "2021/02/03 09:00:00",
labelsFormat : true,
timeZone : -5,
displayFormat: "DHMS",
});

The time until the announcement shows correctly for people in NYC. But for me in Boise, it is 4 hours off.
What could be wrong?
