Here is seconds.c, which uses <time.h> functions to send the day and time out as a list (out of a single list outlet).

/* seconds.c - 
 this object has 1 inlets and 6 outlets
 it responds the 'bang' message in the left inlet
 it responds to the 'assistance' message sent by Max when the mouse is positioned over an inlet or outlet
 (including an assistance method is optional, but strongly sugggested)
