解析utc时，fromNow的瞬间将在5小时内返回 [英] moment fromNow returns in 5 hours when parsing utc

问题描述

尝试使用fromNow的moment.js从服务器上格式化utc时间，但有时我会在"5个小时内"得到.

trying to format utc time from server in time ago using moment.js fromNow but in some occasions I get "in 5 hours" instead.

时间戳-2017-11-29T15:03:21

timestamp from a server - 2017-11-29T15:03:21

var utcTime = new Date(timestamp);
var timeAgo = moment(utcTime).fromNow();    
console.log(timeAgo)

所有日期都过去了，所以我该如何解决这个问题，以便在几个小时内没有时间?

all dates are in past so how can I fix this so I dont get time in a few hours ?

推荐答案

如果要将"2017-11-29T15:03:21"视为UTC，则可以使用moment的 utc 方法，也可以只需在字符串后附加一个"Z"即可.由于您已经在使用moment.js，因此使用moment.js进行解析比内置解析器更可靠:

If you want "2017-11-29T15:03:21" treated as UTC, you can either use moment's utc method or just append a "Z" to the string. Since you're already using moment.js, it's more reliable to parse it with moment.js than the built-in parser:

var timestamp = "2017-11-30T00:20:48";

// Append Z
console.log(moment(timestamp + 'Z').fromNow());

// Use .utc
console.log(moment.utc(timestamp).fromNow());
