Given the date and time, how do you get the time in the era?

Question

I have

int year, month, day, hour, min, sec

How can I get the epoch time in C ++?

I am having a hard time understanding using Boost, any examples or alternative ways to do this?

Fill the tm structure with your values, then call std::mktime()

.

I assume that "get epoch time" means the number of seconds since epoch, ie Unix time_t.

You are making it too hard. Take a look at the time functions in standard libraries .

This boost example should do what you are asking if I understood your problem correctly.

#include <iostream>
#include <sys/time.h>

int main ()
{
  unsigned long int seconds = time(NULL);
  std::cout << seconds << std::endl;
  return 0;
}
