   Static Public Member Functions
       static void set_digits (unsigned num)
           Set number of digits to use when printing (for fractions of seconds).
       static unsigned get_digits ()
           Get the number of digits that is used when printing.

   Friends
       std::ostream & operator<< (std::ostream &s, relative_time t)
           Write the interval to a std::ostream.

Detailed Description

       Time interval.

Constructor & Destructor Documentation

   shevek::relative_time::relative_time (timetypeseconds, unsignednanoseconds)
       Fast constructor. This directly fills the members and is therefore slightly faster than
       the other constructors. However, the others aren't really slow either.

Member Function Documentation

   bool shevek::relative_time::operator!= (relative_timethat) const Compare two intervals. Note
       that this is rarely a useful operation, because minor errors may be introduced by
       computations.
   bool shevek::relative_time::operator== (relative_timethat) const Compare two intervals. Note
       that this is rarely a useful operation, because minor errors may be introduced by
       computations.
