I’m using 1.47, so I would expect this issue to apply.  However, I don’t think this is what I am experiencing. 

 

Right now I am testing out a fix which initially appears to work but I have to fully verify it.

 

void my_class::calculate_packet_statistics ( const struct pcap_pkthdr *header ) {

       frame_interval_.intervalTimeStamp_ = system_clock::from_time_t( static_cast<time_t>( header->ts.tv_sec ) );

 

       // Cast to a duration using the system_clock’s tick period.

       system_clock::duration us_duration = duration_cast< system_clock::duration >( microseconds( header->ts.tv_usec ) );

       frame_interval_.intervalTimeStamp_ += us_duration;

       …

}

 

I would have thought my previous implementation would have done this cast implicitly, but that doesn’t appear to be the case.  I’ll let you know if this works.

 

       frame_interval_.intervalTimeStamp_ =
           system_clock::from_time_t( static_cast<time_t>( header->ts.tv_sec ) ) +
           nanoseconds( header->ts.tv_usec);
