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).
