Thread: time.h ctime and milliseconds

Hi Guys,

I am trying to access the system time using th eheader file time.h and then using ctime(). This is great for the system date and time in seconds and works ok. But I want the time in milliseconds. Does anyone know how to do this or where I am going wrong.

This is my code:

Code:

#include <time.h>

#include <stdio.h>

 

 

int main(void)

{

   time_t lt;

 

   

   char c;

   while(c !='z')

   {

   lt=time(NULL);

 

    printf(ctime(&lt));

 

 

   printf("\nPress Any key to Continue");

   while((c=getchar()) != '\n')

   {

   printf("/n still not equal");

   }

    }

 

 

   return(0);

 

}

Thanks

Andy.

I think you can use the gettimeofday() function or GetSystemTime() if you're on a windows system.

If you have DJGPP you can type "time" and right-click on it to search the help for "time". I think you might also try utime() or something (DJGPP specific).

Why do you want to know the millisecond?

On a POSIX system, see:

clock_t clock()

which returns the number of microseconds since the process was started. (Not milliseconds)

On Win32, see:
DWORD GetTickCount()
