新建cdatetime.cpp

#include <boost/algorithm/string.hpp>#include <string>#include <vector>#include <iostream>#include <ctime>using namespace std;string datetime(){    time_t now = time(0);// 基于当前系统的当前日期/时间    tm *ltm = localtime(&now);    char iyear[50],imonth[50],iday[50],ihour[50],imin[50],isec[50];    sprintf(iyear, "%d",1900 + ltm->tm_year );    sprintf(imonth, "%02d", 1 + ltm->tm_mon );    sprintf(iday, "%02d", ltm->tm_mday );    sprintf(ihour, "%02d", ltm->tm_hour );    sprintf(imin, "%02d",  ltm->tm_min);    sprintf(isec, "%02d",  ltm->tm_sec);    vector<string> sDate{iyear, imonth, iday};    vector<string> sTime{ihour, imin, isec};    string myDate = boost::algorithm::join(sDate, "-") ;    string myTime = boost::algorithm::join(sTime, ":") ;    vector<string> sDateTime{myDate, myTime};    string myDateTime = boost::algorithm::join(sDateTime, " ") ;    return myDateTime;}int main( ){        cout << datetime()<< endl;}

编译：

[root@localhost cdatetime]# g++ cdatetime.cpp -o idatetime -std=gnu++0x

记得加 -std=gnu++0x 参数。
