Date.now() === The Future of i18n

In "19" + date.getYear() - 10, JavaScript was adopted for the web and devs broke time itself. Daylight saving time was ignored, calendars started the week on the wrong day, and meetings were missed. The workarounds piled up: Moment.js shipped every time zone to browsers, devs added "T00:00" to every date string, and "1h 20m" was built by hand. Today, Temporal, Intl.Locale, and Intl.DurationFormat replace them all. This talk shows you how.
