- And they are the only ones that should appear in SMTP mail headers. RFC 1123
- (Requirements for Internet Hosts -- Application and Support) has this to say:
-
- 5.2.14 RFC-822 Date and Time Specification: RFC-822 Section 5
-
- The syntax for the date is hereby changed to:
-
- date = 1*2DIGIT month 2*4DIGIT
-
- All mail software SHOULD use 4-digit years in dates, to ease
- the transition to the next century.
-
- 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.
-
- Finally, note that there is a typo in the definition of "zone"
- in the syntax summary of appendix D; the correct definition
- occurs in Section 3 of RFC-822.
