Javascript 日期格式今天亚洲 GMT+8

Question

In my country, today is 12/15/2022 , I'm from Asia which is gmt+8.

Basically I want my date to be 2022-12-15T00:00:00.000Z instead of showing 2022-12-14T16:00:00.000Z.

here is the code:

 const today = new Date().toLocaleDateString(); console.log(new Date(today));

But I really want it to be exact like this

2022-12-15T00:00:00.000Z

is it possible without using logic "add +8 hours"?

Answer 1

you can force your time zone like this

console.log(new Date(new Date().toLocaleDateString('en', {timeZone: 'Asia/Hong_Kong'})))

Edit: changed toLocaleString to toLocaleDateString this should meet your needs now

Answer 2

One way is to run your code in UTC zone so that you don't accidentally create dates in different time zones. You can set TZ='UTC' environment variable for this.

Otherwise you can create the date like this.

const today = new Date().setUTCHours(0, 0, 0, 0); // note 'today' is a number now
> console.log(new Date(today))
2022-12-15T00:00:00.000Z

Answer 3

You can first convert the date to a local date string, then parse the year, month and day from it to construct the local ISO zero date string:

 const localDate = new Date().toLocaleDateString('en', {timeZone: 'Asia/Hong_Kong'}); console.log('localDate:', localDate); let m = localDate.match(/(\d+)\/(\d+)\/(\d+)/); let localZero = m[3] + '-' + m[1] + '-' + m[2] + 'T00:00:00.000Z'; console.log('localZero:', localZero);

Output:

localDate: 12/15/2022
localZero: 2022-12-15T00:00:00.000Z
