    LocalTime与LocalDate相反,它只代表一个时间,没有日期。 这意味着我们只能获得当天的当前时间,而不是实际日期:

    LocalTime time = LocalTime.now(); // gets the current time
    可以按如下方式format

    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("HH:mm:ss");
    System.out.println(time.format(formatter));
    得到的结果类似如下:

    00:55:58

    1. localtime()函数

     localtime用来获取系统时间,精度为秒

    函数原型

    struct tm *localtime(const time_t * timep)

    头文件

    #include <time.h>

    示例:

    #include <stdio.h>
    #include <sys/time.h>
    #include <time.h>
    #include <unistd.h>
    
    int main() {
      while (1) {
        time_t t = time(NULL);
        struct tm *tm = localtime(&t);
        printf("localtime:%02d/%02d/%02d-%02d:%02d:%02d\n",
               tm->tm_mon + 1, tm->tm_mday, tm->tm_year + 1900,
               tm->tm_hour, tm->tm_min, tm->tm_sec);
        sleep(1);
      }
      return 0;
    }

    运行结果

    localtime:10/04/2013-01:11:33
    localtime:10/04/2013-01:11:34
    localtime:10/04/2013-01:11:35
    localtime:10/03/2013-23:11:36
    localtime:10/03/2013-23:11:37
    localtime:10/03/2013-23:11:38

     

    2.  localtime_r()函数

    用来获取系统时间,运行于linux平台下

    函数原型

    struct tm *localtime_r(const time_t *timep, struct tm *result);

    示例:

    #include <stdio.h>
    #include <sys/time.h>
    #include <time.h>
    #include <unistd.h>
    
    int main() {
      while (1) {
        time_t t = time(NULL);
        struct tm local_tm;
        struct tm *tm = localtime_r(&t, &local_tm);    
        printf("localtime_r:%02d/%02d/%02d-%02d:%02d:%02d\n",
               tm->tm_mon + 1, tm->tm_mday, tm->tm_year + 1900,
               tm->tm_hour, tm->tm_min, tm->tm_sec);
        sleep(1);
      }
      return 0;
    }

    运行结果

    localtime_r:10/04/2013-01:15:37
    localtime_r:10/04/2013-01:15:38
    localtime_r:10/04/2013-01:15:39
    localtime_r:10/04/2013-01:15:40
    localtime_r:10/04/2013-01:15:41
    localtime_r:10/04/2013-01:15:42

     

     3. localtime_s()函数

    用来获取系统时间,运行于windows平台下,与localtime_r只有参数顺序不一样

    #include <iostream>
    #include <time.h>
     
    int main()
    {
    	time_t time_seconds = time(0);
    	struct tm now_time;
    	localtime_s(&now_time,&time_seconds);
     
    	printf("%d-%d-%d %d:%d:%d\n", now_time.tm_year + 1900, now_time.tm_mon + 1,
    		now_time.tm_mday, now_time.tm_hour, now_time.tm_min, now_time.tm_sec);
    }
