How to convert local time to UTC time with moment.js and JavaScript?

To convert local time to UTC time with moment.js and JavaScript, we can use the moment utc and format method.

For instance, we write:

const d = new Date(2022, 1, 1)
const s = moment.utc(d).format("YYYY-MM-DD HH:mm:ss Z")
console.log(s)

to create the date d in local time.

Then we create a UTC moment object from d with moment.utc.

Next, we call format to with a format string that returns the date and time with the time zone.

As a result, s is '2022-02-01 08:00:00 +00:00'.
