在 C 中获取当前时间 [英] Get the current time in C

问题描述

我想获取系统的当前时间.为此，我在 C 中使用以下代码:

I want to get the current time of my system. For that I'm using the following code in C:

time_t now;
struct tm *mytime = localtime(&now); 
if ( strftime(buffer, sizeof buffer, "%X", mytime) )
{
    printf("time1 = "%s"
", buffer);
}

问题是这段代码给出了一些随机时间.此外，随机时间每次都不同.我想要系统的当前时间.

The problem is that this code is giving some random time. Also, the random time is different everytime. I want the current time of my system.

推荐答案

从 这里:

/* localtime example */
#include <stdio.h>
#include <time.h>

int main ()
{
  time_t rawtime;
  struct tm * timeinfo;

  time ( &rawtime );
  timeinfo = localtime ( &rawtime );
  printf ( "Current local time and date: %s", asctime (timeinfo) );
  
  return 0;
}

(只需将 void 添加到 main() 参数列表中即可使其在 C 中工作)

(just add void to the main() arguments list in order for this to work in C)
