implementations... one with three args which is from a draft standard and
is supplied for backwards compatability, and one with two args which
conforms to the final POSIX standard.

This is a kludge since it doesn't use the correct methods for selecting
which ctime_r() (and asctime_r()) implementation to use.  I don't have time
right now to dig up the "right" way.

Instructions are welcome.  :-)
