別のフォーマットまたはパターンを使用して、日付から情報を取得します
var myDate = new Date("2015-06-17 14:24:36");
console.log(moment(myDate).format("YYYY-MM-DD HH:mm:ss"));
console.log("Date: "+moment(myDate).format("YYYY-MM-DD"));
console.log("Year: "+moment(myDate).format("YYYY"));
console.log("Month: "+moment(myDate).format("MM"));
console.log("Month: "+moment(myDate).format("MMMM"));
console.log("Day: "+moment(myDate).format("DD"));
console.log("Day: "+moment(myDate).format("dddd"));
console.log("Time: "+moment(myDate).format("HH:mm")); // Time in24 hour format
console.log("Time: "+moment(myDate).format("hh:mm A"));
