As someone pointed out a week or two ago, some libc functions (asctime was
the one I think) return a pointer to a static char array.  That's one of
the main reasons most libraries aren't thread-safe, but if you aren't
using threads, it's perfectly ok as long as you act on the result before
calling the function again.
