This feature is not Baseline because it does not work in some of the most widely-used browsers.
The Temporal.Now.zonedDateTimeISO() static method returns the current date and time as a Temporal.ZonedDateTime object, in the ISO 8601 calendar and the specified time zone.
Temporal.Now.zonedDateTimeISO() Temporal.Now.zonedDateTimeISO(timeZone)
timeZone OptionalEither a string or a Temporal.ZonedDateTime instance representing the time zone to interpret the system time in. If a Temporal.ZonedDateTime instance, its time zone is used. If a string, it can be a named time zone identifier, an offset time zone identifier, or a date-time string containing a time zone identifier or an offset (see time zones and offsets for more information).
The current date and time in the specified time zone, as a Temporal.ZonedDateTime object using the ISO 8601 calendar. Has the same precision as Temporal.Now.instant().
RangeErrorThrown if the time zone is invalid.
// The current date and time in the system's time zone
const dateTime = Temporal.Now.zonedDateTimeISO();
console.log(dateTime); // e.g.: 2021-10-01T06:12:34.567890123+03:00[Africa/Nairobi]
// The current date and time in the "America/New_York" time zone
const dateTimeInNewYork = Temporal.Now.zonedDateTimeISO("America/New_York");
console.log(dateTimeInNewYork); // e.g.: 2021-09-30T23:12:34.567890123-04:00[America/New_York]
