Temporal.Now.timeZoneId()
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The Temporal.Now.timeZoneId() static method returns a time zone identifier representing the system's current time zone. Most systems will return a primary time zone identifier such as "America/New_York", though offset time zone identifier such as "-04:00" is possible too. The time zone identifier returned is the default time zone used by the other Temporal.Now methods.
Syntax
Temporal.Now.timeZoneId()
Parameters
None.
Return value
A valid time zone identifier representing the system's current time zone. The returned time zone identifier is never a non-primary time zone identifier (alias). For example, it would always return "Asia/Kolkata" (new name) instead of "Asia/Calcutta" (old name). For more information, see time zones and offsets.
If the implementation does not support time zones, the method always returns "UTC".
Examples
Getting the system's current time zone
console.log(Temporal.Now.timeZoneId()); // e.g.: "America/New_York"
