在不更改日期本身的情况下将日期的时区更改为 UTC

Question

Say if the date is:

var now = new Date(); // Tue Apr 19 2022 13:12:41 GMT+0530

I need to change only the timezone to UTC. so Tue Apr 19 2022 13:12:41 GMT+0000 in above case. Things like toISOString() gives actual UTC ie modified date value after adjusting the offset.

Answer 1

You can simply add the timezone difference:

let x = new Date()
x.setMinutes(x.getMinutes() - x.getTimezoneOffset())

Answer 2

You're basically asking for this:

 const now = new Date; const utc = new Date(Date.UTC(now.getFullYear(), now.getMonth(), now.getDate(), now.getHours(), now.getMinutes(), now.getSeconds())); console.log(now, utc);

This creates a date in your local timezone, and then another date with the same year, month, day, hour, minute and second value , but in the UTC timezone.

What sense that makes is another topic…
