数据类型

struct tm {
int tm_sec;         /* seconds */
int tm_min;         /* minutes */
int tm_hour;        /* hours */
int tm_mday;        /* day of the month */
int tm_mon;         /* month */
int tm_year;        /* year */
int tm_wday;        /* day of the week */
int tm_yday;        /* day in the year */

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

void show_tm(struct tm * t)
{
printf("%d-%d-%d", t->tm_year+1900, t->tm_mon+1, t->tm_mday);
printf("  ");
printf("%d:%d:%d\n", t->tm_hour, t->tm_min, t->tm_sec);
}

void main(void)
{
long int curr_time = 0;
struct tm * t;

time(&curr_time);

printf("time=%ld\n", curr_time);

t = localtime(&curr_time);
