c time formattings

Question

How do I format a time_t structure to something like this year-month-day h:m:s, I have already tried using ctime:

time_t t = time((time_t*) NULL); char *t_format = ctime(&t);

but it doesn't give me the desired results

example : 2011-11-10 10:25:03. What I need is a string containing the result so I can write it to a file. Thanks

Use strftime from time.h like so:

char tc[256]; strftime(tc, 256, "%Y-%m-%d %H:%M:%S", tm);

Also call struct tm *tm = localtime(&t); first.

I got it and btw you can write "%Y-%m-%d %H:%M:%S" as "%F %r"

@onica No, %H:%M:%S is not the same as %r, but %T is.
