Of course the greek might better be transcribed as "xronos".  But
we've already been there. :-)

I favor simply "chron_".  It is the basis for "chronometer", is
unlikely to be used already in user programs, and is shorter.

As discussed, hacking and analogy for the name "strfxxx" is a bad idea.

With the above suggestion and the prior work we have "chron_format".
But name discussions are rarely fruitful, once the important criteria 
are exposed; I'm sure Markus is now well-equipped to make sound 
decisions about names.  

Can we discuss the rest of the proposal?

I wonder if it needs a bit more interface for the timezone_t opaque
type, such as a way to find out when the next or previous "summer time"
transition happens/happened, if any.
