info: |
    Using sec-temporal-getdatetimeformatpattern:
    GetDateTimeFormatPattern ( dateStyle, timeStyle, matcher, opt, dataLocaleData, hc )

    1. If dateStyle is not undefined or timeStyle is not undefined, then
      a. For each row in Table 7, except the header row, do
        i. Let prop be the name given in the Property column of the row.
        ii. Let p be opt.[[<prop>]].
        iii. If p is not undefined, then
          1. Throw a TypeError exception.
