如何通过JavaScript将Unix纪元转换为[年，月，日]

Question

我对将存储在变量中的时间戳转换doc.creation_time为格式的需求很小[year,month,day]例子：doc.creation_time=1537492812 应将其转换为[2018,38,Fri]有人可以帮忙吗

Answer 1

var creation_time = 1537492812;

var date = new Date(creation_time * 1000);

var weekday = ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"];

// UTC

console.log(date.getUTCFullYear(), date.getUTCMonth() + 1, weekday[date.getUTCDay()]);

// Local

console.log(date.getFullYear(), date.getMonth() + 1, weekday[date.getDay()]);
