Here's how to create a UTC using Javascript.

function utc() {
	var now = new Date();
	return new Date(convertDateToUTC(now)).toJSON().toString();
}
 
function convertDateToUTC(date) {
	return new Date(
		date.getUTCFullYear(),
		date.getUTCMonth(),
		date.getUTCDate(),
		date.getUTCHours(),
		date.getUTCMinutes(),
		date.getUTCSeconds());
	}
}
