Boost posix time elapsed time
WebApr 14, 2013 · You can get the time using boost::posix_time. See this SO question. Ex: boost::posix_time::time_duration diff = tick - now; diff.total_milliseconds(); You can also use the C++11 chrono, if you can use C++11. Ex: int elapsed_milliseconds = … WebMeasurement starts when boost::timer::cpu_timer is instantiated. You can call the member function format() at any point to get the elapsed time.Example 38.1 displays output in the following format: 0.099170s wall, 0.093601s user + 0.000000s system = 0.093601s CPU (94.4%).. Boost.Timer measures wall and CPU time. The wall time is the time which …

WebJul 11, 2009 · 8. You are using the second_clock to get the current time. As the name implies, it is accurate only to the nearest second. Since your reference time has no fractional seconds the duration fractional seconds always ends up being 0. Use the microsec_clock instead: ptime Now = microsec_clock::universal_time (); http://duoduokou.com/r/17928124161461930841.html
WebThe class boost::posix_time::time_duration the base type responsible for representing a length of time. A duration can be either positive or negative.

WebSystemTime. The system time clock is purely the real time, expressed in milliseconds since Jan 1, 1970 at 0:00 UTC. It's equivalent to the value returned by the C and POSIX time function, with the milliseconds added. This clock type is currently only used on Unix systems that do not support monotonic clocks (see below).
