Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The Temporal.Now.plainDateTimeISO() static method returns the current date and time as a Temporal.PlainDateTime object, in the ISO 8601 calendar and the specified time zone.

Syntax

js
Temporal.Now.plainDateTimeISO()
Temporal.Now.plainDateTimeISO(timeZone)

Parameters

timeZone Optional

Either 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).

Return value

The current date and time in the specified time zone, as a Temporal.PlainDateTime object using the ISO 8601 calendar. Has the same precision as Temporal.Now.instant().

Exceptions

RangeError

Thrown if the time zone is invalid.
