How to compare date in Windows with C

Here is example how I do that in Linux, but in Windows I don't have strptime function anyone can help me solve this problem?

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

time_t to_seconds(const char *date)
{
    struct tm storage = {0, 0, 0, 0, 0, 0, 0, 0, 0};
    char     *p       = NULL;
    time_t    retval  = 0;

    p = (char *) strptime(date, "%d-%b-%Y", &storage);
    if (p == NULL)
    {
        retval = 0;
    }
    else
    {
        retval = mktime(&storage);
    }
    return retval;
}

int main(int argc, char** argv) 
{
    time_t d1 = to_seconds("16-Jun-2015");
    time_t d2 = to_seconds("13-Jun-2015");
    if(d1 > d2)
    {
        printf("date 1 > date 2");
    }
}
