Integrate a lighter datetime formatter with i18n support

[jperucello]

Is your feature request related to a problem? Please describe.
Moment.js is now deprecated, cannot handle timezone when running on Monitors / Newman and it's heavy.

Describe the solution you'd like
I'd like to have a non-deprecated and lighter library to manipulate date+timestamp AND timezone on Postman

Describe alternatives you've considered

• Intl support
• • Any of the following:
    https://date-fns.org/
    https://day.js.org/
    https://moment.github.io/luxon/

Found this issue as I'm interested in date-fns (or any other moment alternative) as well. Is there any update?

Hey folks!

Postman now supports importing external packages from NPM directly into your scripts. You can now use any package of your preference to work with dates and times:

luxon:

const { DateTime } = pm.require("npm:luxon");

function logTime(zone, label) {
  const time = DateTime.now().setZone(zone);
  console.log(`Current time in ${label}:`, time.toFormat("yyyy-MM-dd HH:mm:ss ZZZZ"));
}

logTime("Asia/Kolkata", "India");
logTime("America/New_York", "NY");

date-fns:

const dateFns = pm.require('npm:date-fns');

dayjs:

const dayjs = pm.require('npm:dayjs');

Note: We don’t plan to support this in newman, but it will be available soon in the Postman CLI and Monitors.

I’ll close this ticket for now — feel free to open a new one if you run into anything or this does not fulfill your use case. 🚀
