how to get minute of the system time from C program - c

Question

how to get minute of the system time from C program? can I use gettimeoftheday?? If anyone has C program which can do this please share, I'm a newbie.Thanks
some sample code
#include <sys/time.h>
#include <time.h>
#include <stdlib.h>
#include <stdio.h>
int main(void)
{
char buffer[30];
struct timeval tv;
time_t curtime;
gettimeofday(&tv, NULL);
curtime=tv.tv_sec;
strftime(buffer,30,"%m-%d-%Y %T.",localtime(&curtime));
printf("%s%ld\n",buffer,tv.tv_usec);
return 0;
}

Answer 1

You can use strftime to get only the minutes part :
#include <time.h>
#include <stdlib.h>
#include <stdio.h>
int main(void)
{
char buffer[0x100];
time_t curtime;
// Don't forget to check the return value !
curtime = time(NULL);
if (curtime == -1)
{
perror("time()");
return 1;
}
strftime(buffer,0x100,"%M",localtime(&curtime));
printf("minutes: %s\n", buffer);
return 0;
}
No need to use gettimeofday here, use it only if you want a precision better than seconds.

#include <stdio.h>
#include <time.h>
int main()
{
time_t curtime;
char buffer[30];
struct tm* tm_info;
time(&curtime);
tm_info = localtime(&curtime);
strftime(buffer, 30, "%Y-%m-%d %H:%M:%S", tm_info);
puts(buffer);
return 0;
}
%Y:- will print year
%m:- will print Month
%d:- will print day
%H:- will print Hour
%M:- will print Minute
%S:- will print Second
