Linux系统编程（时间跟日期）

Linux系统编程（时间和日期）

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

int main(void)
{
	int i;
	time_t the_time;
	
	for(i = 1; i<= 10; i++)
	{
		the_time = time((time_t *)0);
		printf("The time is %ld\n", the_time);
		sleep(2);

	}
	exit(0);
}

执行的结果:

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

int main()
{
	struct tm *tm_ptr;
	time_t the_time;
	(void)time(&the_time);
	tm_ptr = gmtime(&the_time);

	printf("Raw time is %ld\n",the_time);
	printf("gmtime gives:\n");
	printf("data:%02d/%02d/%02d\n",tm_ptr->tm_year,tm_ptr->tm_mon+1,tm_ptr->tm_mday);

	printf("time:%02d/%02d/%02d\n",tm_ptr->tm_hour,tm_ptr->tm_min,tm_ptr->tm_sec);
	exit(0);
}
