    name: extract
    description:  >-
      Extract portion of a date/time value.
      * YEAR Return the year.

        its days in January.
      * US_YEAR Return the US epidemiological year. First week of US epidemiological year has the majority (4 or more)

        epidemiological week starts on Sunday.
      * QUARTER Return the number of the quarter within the year. January 1 through March 31 map to the first quarter,

      * MONDAY_DAY_OF_WEEK Return the number of the day within the week, from Monday (first day) to Sunday (seventh
        day).
      * SUNDAY_DAY_OF_WEEK Return the number of the day within the week, from Sunday (first day) to Saturday (seventh

      * HOUR Return the hour (0-23).
      * MINUTE Return the minute (0-59).
      * SECOND Return the second (0-59).
      * MILLISECOND Return number of milliseconds since the last full second.
      * MICROSECOND Return number of microseconds since the last full millisecond.
      * NANOSECOND Return number of nanoseconds since the last full microsecond.
      * SUBSECOND Return number of microseconds since the last full second of the given timestamp.
      * UNIX_TIME Return number of seconds that have elapsed since 1970-01-01 00:00:00 UTC, ignoring leap seconds.
      * TIMEZONE_OFFSET Return number of seconds of timezone offset to UTC.

      The range of values returned for QUARTER, MONTH, DAY, DAY_OF_YEAR, MONDAY_DAY_OF_WEEK, SUNDAY_DAY_OF_WEEK,
      MONDAY_WEEK, SUNDAY_WEEK, ISO_WEEK, and US_WEEK depends on whether counting starts at 1 or 0. This is governed
      by the indexing option.

      When indexing is ONE:
      * QUARTER returns values in range 1-4
      * MONTH returns values in range 1-12
      * DAY returns values in range 1-31
      * DAY_OF_YEAR returns values in range 1-366
      * MONDAY_DAY_OF_WEEK and SUNDAY_DAY_OF_WEEK return values in range 1-7
      * MONDAY_WEEK, SUNDAY_WEEK, ISO_WEEK, and US_WEEK return values in range 1-53

      When indexing is ZERO:
      * QUARTER returns values in range 0-3
      * MONTH returns values in range 0-11
      * DAY returns values in range 0-30
      * DAY_OF_YEAR returns values in range 0-365
      * MONDAY_DAY_OF_WEEK and SUNDAY_DAY_OF_WEEK return values in range 0-6
      * MONDAY_WEEK, SUNDAY_WEEK, ISO_WEEK, and US_WEEK return values in range 0-52

      The indexing option must be specified when the component is QUARTER, MONTH, DAY, DAY_OF_YEAR,
      MONDAY_DAY_OF_WEEK, SUNDAY_DAY_OF_WEEK, MONDAY_WEEK, SUNDAY_WEEK, ISO_WEEK, or US_WEEK. The
      indexing option cannot be specified when the component is YEAR, ISO_YEAR, US_YEAR, HOUR, MINUTE, SECOND,
      MILLISECOND, MICROSECOND, SUBSECOND, UNIX_TIME, or TIMEZONE_OFFSET.

      Timezone strings must be as defined by IANA timezone database (https://www.iana.org/time-zones).
      Examples: "Pacific/Marquesas", "Etc/GMT+1".
      If timezone is invalid an error is thrown.
