| // |
| // - we do not recognize a folding white space (FWS) or comment (CFWS). |
| // for our purposes, instead, we accept any sequence of Unicode |
| // white space characters (denoted here to `S`). For comments, we accept |
| // any text within parentheses while respecting escaped parentheses. |
| // Any actual RFC 2822 parser is expected to parse FWS and/or CFWS themselves |

| // - two-digit year < 50 should be interpreted by adding 2000. |
| // two-digit year >= 50 or three-digit year should be interpreted |
| // by adding 1900. note that four-or-more-digit years less than 1000 |

| // - mismatching day-of-week is always an error, which is consistent to |

| // - zones can range from `-9959` to `+9959`, but `FixedOffset` does not |
| // support offsets larger than 24 hours. this is not *that* problematic |
| // since we do not directly go to a `DateTime` so one can recover |
