Hi
How about using time() and ctime() functions.

regards

#include <stdio.h>
#include <sys/time.h>

#include <unistd.h>

void print_time ()
{
        struct timeval tv;
        struct tm* ptm;
        char time_string[40];
        long milliseconds;

        gettimeofday (&tv, NULL);
        ptm = localtime (&tv.tv_sec);
        strftime (time_string, sizeof (time_string), "%Y-%m-%d %H:%M:%S",
ptm);
        milliseconds = tv.tv_usec / 1000;
        printf ("%s.%03ld\n", time_string, milliseconds);
}


main()
{
        print_time();
}

I hope this helps.

time conversion

Hi,

I had searched the net on how to convert unsigned long timestamp
to human readable format or maybe in struct timeval format. Any sample 
code that you can share would be greatly appreciated.
Thanks.

#include <stdio.h>
#include <sys/time.h>
#include <time.h>
#include <unistd.h>

void print_time ()
{
        struct timeval tv;
        struct tm* ptm;
        char time_string[40];
        long milliseconds;

        gettimeofday (&tv, NULL);
        ptm = localtime (&tv.tv_sec);
        strftime (time_string, sizeof (time_string), "%Y-%m-%d %H:%M:%S",
ptm);
        milliseconds = tv.tv_usec / 1000;
        printf ("%s.%03ld\n", time_string, milliseconds);
}


main()
{
        print_time();
}

I hope this helps.

I think this may serve u  r purpose

#include <stdio.h>
#include <sys/time.h>
#include <time.h>
#include <unistd.h>



int main()
{
	time_t t;  //Number in Unsigned format
  	printf("% u \n ",t);
	time(&t);
	printf("%s",ctime(&t)); //  Time in Human readable format
	return 0;
}
