C - Printing only selected information from mktime?

I am kinda stuck here with the mktime function and I would appreciate any help I can get.

So what I am doing is, having the user input a year, month and day and then run the tm structure to calculate everything like this:

struct tm time;

time_t t; 

time.tm_year = year - 1900;
time.tm_mon = month - 1;
time.tm_mday = day;
time.tm_hour = 0;
time.tm_min = 0;
time.tm_sec = 0;
time.tm_isdst = -1;

And then I run the mktime function and set it equal to t:

t = mktime(&time);

And then I run the print function like this:

printf("%s", ctime(&t));

However, what I am getting via this method is this for example:

Sat Aug 23 00:00:00 2013

But what I would like the final time format to look like is this:

Mon 2013 02 11

How would I go about doing this? I think my approach with the ctime function is not really right.

Maybe I should use the strftime function?

Note that I don't need to print the current time though.

Thanks, have a good one : )

You can use strftime for this. Here is an example:

char str[50];
struct tm *tm_info = localtime(&t);
strftime(str, 50, "%a %G %m %d", tm_info);

Then you can use printf("%s\n", str) to output the formatted date.

Thanks to Xis88 for the format.
