You think I do? :)

I was referring to the C code implementing current-time (which, btw, has been
changed in latest):

,----
| DEFUN ("current-time", Fcurrent_time, Scurrent_time, 0, 0, 0,
|        doc: /* Return the current time, as the number of seconds since 
1970-01-01 00:00:00.
| The time is returned as a list of three integers.  The first has the
| most significant 16 bits of the seconds, while the second has the
| least significant 16 bits.  The third integer gives the microsecond

| }
