返回值
此函数返回一个指向tm结构的指针,其中填充了时间信息。以下是tm结构信息-
struct tm {
int tm_sec; /* seconds, range 0 to 59 */
int tm_min; /* minutes, range 0 to 59 */
int tm_hour; /* hours, range 0 to 23 */
int tm_mday; /* day of the month, range 1 to 31 */
int tm_mon; /* month, range 0 to 11 */
int tm_year; /* The number of years since 1900 */
int tm_wday; /* day of the week, range 0 to 6 */
int tm_yday; /* day in the year, range 0 to 365 */
int tm_isdst; /* daylight saving time */
};
示例
以下示例显示localtime函数的用法-
#include <stdio.h>
#include <time.h>
int main () {
time_t rawtime;
struct tm *info;
time( &rawtime );
info = localtime( &rawtime );
printf("Current local time and date: %s", asctime(info));
return(0);
}
尝试一下
让我们编译并运行上面的程序,它将产生以下结果。
Current local time and date: Thu Aug 23 09:12:05 2012
