I have the following code

const timeInTz = moment.tz('2022-01-01 21:00', 'America/New_York').utc().format('HH:mm');
alert(timeInTz);

I'm trying to convert from eastern time to utc and then only get the time in the output date, but the result is not a UTC date but actually eastern time. The code is not converting the date from one timezone to another. Can someone please help?
