I do not believe that I am necessarily familiar with the article you
remember. "C++ Report" from SIGS was discontinued (or supposedly absorbed
into sister "Journal of Object-Oriented Programming" but most of
its writers moved to "CUJ") in August 2000. Rival "C/C++ User's
Journal" ("CUJ") is currently owned by CMP Media which bought it and
sisters off Miller Freeman circa Spring 2000; inheriter of M & T
properties probably in the early/mid-1990s. Before being "C/C++ User's
Journal" it was "C User's Journal" (hence still called "CUJ").

"CUJ" has a very well priced CD of about a decade of its most recent
articles.

Certainly capitialising on the explorations of others is a reasonable
approach. With regards to "some date stuff" as an issue for C libraries,
more recently than you are probably thinking there was a blunder with the
new C Standard C99 (as opposed to the exStandard C89 and the only
Standard C++). Serious incompatibilities with POSIX for time formats were
discovered before the publication of C99 but after the Final Draft
Internatonal Standard had been passed (and therefore immutable under the
rules until it was published as an International Standard at which point
defects could officially be tackled in revisions).

If Peter Hermann can track down a copy of "Calendrical Calculations" he
may find a lot of useful things in there he does not have already. He
might not.

Good luck,
Colin Paul Gloster

step # 1 is to build on the work of others. The C/C++ report (or is
it "C/C++ Journal"?) had an article a couple of years back on the
internationalisation of the C libraries, which included some date
stuff as well.

I think we should learn from their stuff before recreating all their
thinking, and perhaps even making  mistakes they they recognised and
avoided.
