time_t和struct tm之间的转换

time_t到struct tm的转换：

#include <time.h>
struct tm *localtime(const time_t *timep);

#include <time.h>
time_t mktime(struct tm *tm);

示例程序；

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main (int argc, char **argv)
{
    int i;
    time_t timer[4];
    struct tm tm, *p;


    tm.tm_year = 2015;
    tm.tm_mon = 2;
    tm.tm_mday = 23;
    tm.tm_hour = 8;
    tm.tm_min = 22;
    tm.tm_sec = 0;
    for(i = 0; i < 4; i++){
        timer[i] = mktime(&tm);
        printf ("timer[%d] = %ld\n", i, timer[i]);
        p = localtime(&timer[i]);
        printf("%d-%d-%d-%d-%d-%d\n",
                p->tm_year,
                p->tm_mon,
                p->tm_mday,
                p->tm_hour,
                p->tm_min,
                p->tm_sec);
    }


    return 0;
} /* ----- End of main() ----- */
