Question

2020-08-01 11:53:25.85088067 +0000 UTC m=+154637.818754072我收到这种格式的时间，需要帮助才能用 JavaScript 将其转换为 2020 年 8 月 1 日上午 11:53

Answer 1

您可以使用矩库。试试这个：

let moment = require('moment');

let dateString = "2020-08-01 11:53:25.85088067 +0000 UTC m=+154637.818754072"

dateString = dateString.split("+")[0];

let date = new Date(dateString);

let formattedDate = moment(date).format('Do MMMM YYYY, h:mm:ss a');

console.log(formattedDate); //1st August  2020, 11:53:25 am

Answer 2

const dateTimeString = "2020-08-01 11:53:25.85088067 +0000 UTC m=+154637.818754072"

const dateTimeArray = dateTimeString.split(' ')

const [date, time] = dateTimeArray

const dateArray = date.split('-')

const timeArray = time.split(':')

const [year, month, day] = dateArray

const [hour, minute, second] = timeArray

const utcDate = new Date(Date.UTC(year, month - 1, day, hour, minute, second));

console.log(utcDate.toUTCString())

console.log(utcDate.getTime() / 1000)

Answer 3

如果你想要秒中的值，那么：

Math.floor(新日期('2011-03-29 17:06:21 UTC') / 1000); 它会给你秒的 Unix 时间..（在上面的例子中：1301418381）

如果你想要完整的日期对象：根据 mdn ( https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/UTC ) 使用这个：

var dateString = "2020-08-01 11:53:25.85088067 +0000 UTC m=+154637.818754072"

dateString.toUTCString()
