In general, you probably want to cast the SysTime to a DateTime

yes, I would agree ;-)
Of course the intention was not really to just format it the same 
way as Clock.currTime() does it, but rather to provide a way to 
more easily customise the format, however one likes, whenever one 
likes..

e.g.the following small change to the format string would make it 
return: 20171213_1924_41

(that's more like something I'd use)

  return
            format("%04s%02s%02s_%02s%02s_%02s",
                (d.year),
                to!(int)(d.month),
                (d.day),
                (d.hour),
                (d.minute),
                (d.second)
                );
