[javascript]5分前の日時を取得する

More than 1 year has passed since last update.

5分前の年月日&日時取得の際、取得した時の時刻が0:00の場合、日付も時間(hour)も変わってしまうためのめも。

var now = new Date();
var before5min_unix = now.getTime() - 300000; //ミリ秒なので(300秒*1000)
var before5min = new Date(before5min_unix);

var year = before5min.getFullYear();
var month = before5min.getMonth()+1;
var date = before5min.getDate();
var hours = before5min.getHours();
var minute = before5min.getMinutes();

console.log(year+'/'+month+'/'+date+'/ '+hours+':'+minute);
