Class template microsec_clock

boost::date_time::microsec_clock — A clock providing microsecond level resolution.

Synopsis

template<typename time_type> 
class microsec_clock {
public:
  // types
  typedef time_type::date_type          date_type;             
  typedef time_type::time_duration_type time_duration_type;    
  typedef time_duration_type::rep_type  resolution_traits_type;

  // public static functions
  template<typename time_zone_type> 
    static time_type local_time(shared_ptr< time_zone_type >) ;
  static time_type local_time() ;
  static time_type universal_time() ;

  // private static functions
  static time_type create_time(TZ_FOR_CREATE) ;
  static time_type local_time() ;
  static time_type universal_time() ;
  static time_type create_time(FILETIME &, TZ_FOR_CREATE) ;
};

Description

A high precision clock that measures the local time at a resolution up to microseconds and adjusts to the resolution of the time system. For example, for the a library configuration with nano second resolution, the last 3 places of the fractional seconds will always be 000 since there are 1000 nano-seconds in a micro second.
