  • timezone_value

    A STRING literal. The ID of session local timezone in the format of either region-based zone IDs or zone offsets. Region IDs must have the form ‘area/city’, such as ‘America/Los_Angeles’. Zone offsets must be in the format ‘(+|-)HH’, ‘(+|-)HH:mm’ or ‘(+|-)HH:mm:ss’, e.g ‘-08’, ‘+01:00’ or ‘-13:33:33’. Also, ‘UTC’ and ‘Z’ are supported as aliases of ‘+00:00’. Other short names are not recommended to use because they can be ambiguous.

    For a list of valid timezones, see List of tz database time zones.

  • interval literal

    The interval literal represents the difference between the session time zone to the ‘UTC’. It must be in the range of [-18, 18] hours and max to second precision, for example: INTERVAL '15:40:32' HOUR TO SECOND.
