This isn’t an SDL question. Track down the C Programming FAQ (it’s both
in book form, and online), and I believe you’ll find the answer.

Good luck!

You could have at least told him he probably wants
ctime :slight_smile: He could be forgiven thinking that this is
platform dependent and therefore handled in SDL.

Sorry, I was rushing off to a doctor’s appointment! :^P
Anyway, the C FAQ is really useful. :wink:

—end quoted text—
Take a look at the manpages of the functions:

time_t time(time_t *t);
struct tm *gmtime(const time_t *timep);
struct tm *localtime(const time_t *timep);

Making:
time_t t;
struct tm *tm;
time (&t);
tm = localtime (&t);

you will have at tm structure:
struct tm {
int tm_sec; /* seconds /
int tm_min; / minutes /
int tm_hour; / hours /
int tm_mday; / day of the month /
int tm_mon; / month /
int tm_year; / year /
int tm_wday; / day of the week /
int tm_yday; / day in the year /
int tm_isdst; / daylight saving time */
};
and then you just choose what you want… :slight_smile:
