Method of converting timestamp to current time in jQuery (use directly)

function formatDateTime(inputTime) {
	var date = new Date(inputTime);
	var y = date.getFullYear();
	var m = date.getMonth() + 1;
	m = m < 10 ? ('0' + m) : m;
	var d = date.getDate();
	d = d < 10 ? ('0' + d) : d;
	var h = date.getHours();
	h = h < 10 ? ('0' + h) : h;
	var minute = date.getMinutes();
	var second = date.getSeconds();
	minute = minute < 10 ? ('0' + minute) : minute;
	second = second < 10 ? ('0' + second) : second;
	return y + '-' + m + '-' + d + ' ' + h + ':' + minute + ':' + second;
};

As shown in the figure below, directly declare the method in the global variable and call it directly.
