Linux c++获取当前系统时间并格式化输出

#include <string>
#include <time.h>
#include <iostream>

using namespace std;
 
string getTime()
{
    time_t timep;
    time (&timep);
    char tmp[64];
    strftime(tmp, sizeof(tmp), "%Y-%m-%d %H:%M:%S",localtime(&timep));
    return tmp;
}
 
int main(){
    string   time = getTime();
    cout << time << endl;
 
    return 0;
}

编译：g++ date.cpp -o date

执行：./date

结果:2019-09-09 17:06:32
