IIRC, the abbreviations are deprecated, and have been for some time.
This might explain the lack of a map. Here's what the new version of RFC
822 will say:
4.3. Obsolete Date and Time
The syntax for the obsolete date format allows a 2 digit year in the
date field and allows for a list of alphabetic time zone specifications
that were used in earlier versions of this standard.
Even when RFC 1123 was written, it said:
There is a strong trend towards the use of numeric timezone
indicators, and implementations SHOULD use numeric timezones
instead of timezone names. However, all implementations MUST
accept either notation. If timezone names are used, they MUST
be exactly as defined in RFC-822.
The military time zones are specified incorrectly in RFC-822:
they count the wrong way from UT (the signs are reversed). As
a result, military time zones in RFC-822 headers carry no
information.
But, of course, people continue to use them... (Exim does not).
