To quote from this same list's archives, in 1987 (views may not reflect
the now current views of the then participants):

Subject: List structure and standards making
While the list has been discussing time and timezones in context
of the IEEE P1003 standards committee, people have lost sight of
X3J11 which is much more important and further along towards
casting into concrete. (Dramatic effect) As we now talk, the
concrete has been laid and is hardening. (End drama).
People should get out their X3J11 Draft Proposed American
Standard for Information Systems -- Programming Language C (Dated
October 1, 1986). This standard is ALREADY entering the
balloting process. Please turn to page 151 and following:
Section 4.12 -- Date and Time.
The standard ALREADY covers clock_t, time_t, struct tm (without
new strings or fields!!), clock(), time(), difftime(), mktime(),
asctime(), ctime(), gmtime(), localtime(), strftime().
Thus the current discussions on the whole time subject are
rapidly becomming academic as the ANSI C is already spoken and
the C standard is currently in the comment phase -- send a
comment and proposed change of ruling. The next phase is
balloting and trial use.

Dennis,
The discussions are certainly NOT becoming academic. There are a lot
of people who just don't care what X3J11 says; who believe that X3J11
is irreparably broken, and intend to ignore it into the indefinite
future. It may well be that ``the ANSI C is already spoken.''
For my money, the ANSI C is already buggered.

We seem in danger of heading the same way again.
