Hi Rich,

Try this:
printf (  "%ld seconds into the epoch\n", (long int)now.tv_sec );

Thanks, I don't know why but it takes me a bit of effort to accept the need for a cast--especially after all the effort that went into typedefs for int32_t, __time_t, etc.

I rationalize the cast as producing "what printf" expects rather than what "the data is". It also helps to realize that it will work with 64-bit architectures, no matter what __time_t is defined to be.
