| Conflicting properties of dateStyle must be rejected with a TypeError for the options argument |
| 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. |
