@joshuasosa,
You can use toUTCString() method to convert a Javascript timestamp values into UTC format. Please refer to this stack overflow article for more information.
Also if you like to display time in a particular timezone, you can use the toLocaleString() method to convert a Date object to a string, using locale settings. You can output dates that are in UTC or local time to a specific timezone by passing timeZone option to toLocaleString().
