Hi,

Here you are comparing the gmtime() output to The "date" command.

see the man pages of gmtime().This will give you the time in UTC format.
use localtime(). Gives same as your "date" output.

I have modified your code .Know it gives the 
The code below.

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

int main(void) {
 struct tm *tm_ptr;
 time_t the_time;

 (void)time(&the_time);
 tm_ptr = localtime(&the_time);

 printf("tm_ptr->tm_hour = %d\n", tm_ptr->tm_hour);

 return 0;
}


Cheers

Subject: <time.h>: gmtime keeps giving the same time ....


Hello,

Output from the date `command` in my terminal:
Thu May  8 21:42:28 CEST 2003

Output from my `problem'_program.c
19

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

int main(void) {
 struct tm *tm_ptr;
 time_t the_time;

 (void)time(&the_time);
 tm_ptr = gmtime(&the_time);

 printf("tm_ptr->tm_hour = %d\n", tm_ptr->tm_hour);

 return 0;
}

No matter what I do, this C - code keeps giving me as output 19.

Is my system messed up or my head ?

Any thoughts are more than welcome

Thnkx....

J.

Thank you for the complete reply ! 

I understand what I did wrong, and how to do it better next time.

Merci....
