I'm getting pretty ticked about this, which damn line is offending the
listserv software?

According to most systems, the asctime() function returns a pointer to
statically allocated string, "which might be overwritten by subsequent
calls to any of the date and time functions".

This is how GNU's libc is, and how it is in Solaris.

If you want a thread-safe version, on Solaris is has a list of time_r
functions, asctime_r is "thread-safe" in that you supply your own buffer to
write the information to.
