Question

I'm trying to get a UTC time string in YYYY-MM-DD HH:MM:SS format but when using moment it's just giving the local input time back, what am I doing wrong?

moment('2019-04-16 22:00:00:').utc()

This returns a moment object with the value of 2019-04-16 22:00:00

Answer 1

这是一个将本地时间转换为UTC的有效示例。签出

var local = moment.utc().local().format("YYYY-MM-DD HH:mm:ss");
console.log(local, "- local");
var date = moment(local).utc().format("YYYY-MM-DD HH:mm:ss");
console.log(date, "- local now in UTC");

您可以使用moment-timezone库，可以输入要转换为UTC的任何时区。

var input = "2019-04-16 22:00:00"
var format   = "YYYY-MM-DD HH:mm:ss";
var yourzone  = "Asia/Seoul";

var yourtime = moment.tz(input, format, yourzone);

// convert to utc
yourtime.utc();

// format output
var result = yourtime.format(format) 
console.log(result)

var input = "2019-04-16 22:00:00"
var format   = "YYYY-MM-DD HH:mm:ss";
var yourzone  = "Asia/Seoul";

var yourtime = moment.tz(input, format, yourzone);

// convert to utc
yourtime.utc();

// format output
var result = yourtime.format(format) 
console.log(result)
