   You can't. As far as the language is concerned, `time_t` is intended to   
   be an opaque type. It has to be a real type, so it is either an integer   
   of a plain floating-point type. But other than that nothing is known   
   about it. There's really no point in printing it.   
      
   If you still want to, you can do it in some implementation-specific way.   
   Which still immediately means that you can't do it "reliably", if I   
   understand what you mean correctly.
