I was curious about this too, so I took a look at the source code and found the following:
Code:
/*----------------------------------------------------------------------------
  Display on Standard Output the value of the Hardware Clock, which is described by these arguments:
...
     referenceTime: The system time at which this program started (so,the moment at which the user wanted to know the time)

     readTime: The system time at which we read the clock.
...
*/
...
float const displayDelay = time_diff(readTime, referenceTime);
...  
 printf("%s %s  %.6f seconds %s\n", 
               ctime2(hclockTime),
               synchronized ? "" : "+", -(displayDelay), 
               brokenTime.tm_isdst ? tzname[1] : tzname[0]);
┐Claro?
