date representation standards before ISO 2014 and ISO 8601

[Eric Smith]

In a lot of contexts that predate widespread adoption of ISO 2014 and
ISO 8601 (and their relatives), I've seen dates represented in a form
such as "02-MAR-79" or "02-MAR-1979". This is similar to the RFC
822/1123 date format, except that those RFCs don't use a hyphen
between the components, and use mixed-case for the month.

Was there ever an official standard defining such a representation?
