average estimated time

[rafae11]

while ( nummessage > 0)
{
// start time
ptime t1 = boost::posix_time::second_clock::local_time();

// function 
Readlogs(start,incrementer,h,m_pathname);			

// end time
ptime t2 = boost::posix_time::second_clock::local_time();

time_duration td = t2 - t1;

// time it takes to process 1 message
double time_for_one_message = td.total_microseconds() / 8;

// time remaining
double remaining_time = time_for_one_message * nummessage;

// display time
time_duration remaining_td(0,0,(remaining_time/1000000));
}

for the most part its quite accurate.
how would i take an average measurement of the process above inside the loop to make my output more stable?

sometimes it jumps from 1:00 to 0:00.

Store the last X times in a deque or circular_buffer and take the average every time.
