I cannot speak for them, but Robert Elz has brought up the idea of
an entirely new interface, and i personally think that *if*
anything would be done, then it should be a real object based
approach.

Something "datetime" alike, what many scripting+ languages and
libraries offer, with defined arithmetic, most often with
dedicated functions like add_months|years|days|microseconds, what
do i know.  Ie no more +1900 at time, no more such things, but
accessors and questions onto an object interface that does not
modify global data.  That would surely be a good new foundation.
And then there needs to be some calendar object to be able to
truly reflect cultural date and time differences.  I never was
able (nor did i have the need) to work with these real things.

It is hard to imagine that ISO C does anything such.
