Also, Clive Feather [...] has proposed that a new <time.h> section be written to address these problems. I welcome this proposal, and would like to contribute. However, I believe that it's too late in the standardization process to introduce major improvements to <time.h>, as there will be insufficient time to gain implementation experience with these changes, experience that is needed for proper review.

I also think it may be too late for incorporating huge changes in the time functions, as Clive lastly proposed. I am also reluctant to introduce such changes *after* the FCD stage (correct me if I am wrong, but I see it as contrary to what a FCD should be, and it may raise virulent formal objections later, at FDIS stage).

We can do any changes we like from the FCD ballot, this is a normal CD ballot and we are not restricted to minor changes. Keld
