使用 Javascript 将日期转换为纪元时间戳

Question

I have date in MM/DD/YYYY HH:MM AM/PM format Example 07/27/2022 10:36 AM I want to convert it into Epoch timestamp which is 1658898360

Answer 1

The Date object in Javascript is notoriously tricky to work with, and date parsing is sadly lacking. Simply using

const dateString = "07/27/2022 10:36 AM"
const date = new Date(dateString)

might work, but not reliably.

One option is to use the date-fns library :

import { parse, getUnixTime } from 'date-fns'

const date = parse('07/27/2022 10:36 AM', 'MM/dd/yyyy hh:mm a', new Date())
const epoch = getUnixTime(date)

Answer 2

You can use the date.getTime method to convert it to epoch:

 const date = new Date("07/27/2022 10:36 AM"); console.log(date.getTime() / 1000)

Just be sure that you (or the client) is in the same timezone you are expecting (IST in this case).

Or just add GMT+5:30 to ensure this.

 const date = new Date("07/27/2022 10:36 AM GMT+5:30"); console.log(date.getTime() / 1000)

Answer 3

You can use below sample code:

 function epoch (date) { return Date.parse(date) } const dateToday = new Date() const timestamp = epoch(dateToday) console.log( timestamp )
