/* re. [RFC7231 section-7.1.1.1](https://tools.ietf.org/html/rfc7231#section-7.1.1.1)
"HTTP servers and client MUST accept all three HTTP-date formats" which are IMF-fixdate,
obsolete RFC 850 format and ANSI C's asctime() format.
ISO 8601 format is common in JSON and XML fields, defined by RFC 3339 as a timestamp format.
Though not mandated, we check string against them to allow using Date(rfcString:) in
wider and more general sitations.
We use RFC 822 instead of RFC 1123 to convert from string because NSDateFormatter can parse
both 2-digit and 4-digit year correctly when `dateFormat` year is 2-digit.
These values are sorted by frequency.
