当地时间用毫秒 [英] Local time with milliseconds

问题描述

我如何能得到当前的时间与库提振。我可以这样做：

how can I get current time with library boost. I can do this:

ptime now = boost::posix_timesecond_clock::local_time();
tm d_tm = to_tm(now);

但 TM 结构的最后一个时间单位为秒，我需要在毫秒。我能得到当前的时间毫秒？

But the last time unit of tm structure is second and I need in millisecond. Can I get current time with milliseconds?

推荐答案

看<一个href=\"http://www.boost.org/doc/libs/1_43_0/doc/html/date_time/posix_time.html\">boost::posix_time::microsec_clock::local_time()

#include <boost/date_time/posix_time/posix_time_types.hpp>

#include <iostream>

int
main()
{
    boost::posix_time::ptime time = boost::posix_time::microsec_clock::local_time();
    boost::posix_time::time_duration duration( time.time_of_day() );
    std::cout << duration.total_milliseconds() << std::endl;

    return 0;
}
