boost获取时间并格式化的方法

#include <boost/date_time/gregorian/gregorian.hpp> #define BOOST_DATE_TIME_SOURCE    std::string strTime = boost::gregorian::to_iso_string(/ boost::gregorian::day_clock::local_day());    std::cout << strTime.c_str() << std::endl;

#include <boost/date_time/posix_time/posix_time.hpp> #define BOOST_DATE_TIME_SOURCE    std::string strTime = boost::posix_time::to_iso_string(/ boost::posix_time::second_clock::local_time());    // 这时候strTime里存放时间的格式是YYYYMMDDTHHMMSS，日期和时间用大写字母T隔开了    int pos = strTime.find('T'); strTime.replace(pos,1,std::string("-")); strTime.replace(pos + 3,0,std::string(":")); strTime.replace(pos + 6,0,std::string(":"));    std::cout << strTime.c_str() << std::endl; 

#include <boost/date_time/posix_time/posix_time.hpp> #include <boost/thread.hpp> #define BOOST_DATE_TIME_SOURCE  boost::posix_time::ptime time_now,time_now1; boost::posix_time::millisec_posix_time_system_config::time_duration_type time_elapse;  // 这里为微秒为单位;这里可以将microsec_clock替换成second_clock以秒为单位; time_now = boost::posix_time::microsec_clock::universal_time();  // sleep 100毫秒; boost::this_thread::sleep(boost::posix_time::millisec(100));  time_now1 = boost::posix_time::microsec_clock::universal_time();  time_elapse = time_now1 - time_now;  // 类似GetTickCount，只是这边得到的是2个时间的ticket值的差，以微秒为单位; int ticks = time_elapse.ticks();  // 得到两个时间间隔的秒数; int sec = time_elapse.total_seconds();
