>strftime() looks like strftime(char *str, size_t maxsize, const char *fmt, struct tm *time) so I would assume you'd use it something like //you can initialize this from a time_t, but i'm cheating for the sake of email var timeval = Time(); timeval.minute = 1; timeval.hour = 15; //string needs some allocated room, because strftime() is expecting a char[] + len and not char* // and char[80] doesn't seem to work at last check. so I'm cheating again. string date_string = " "; timeval.strftime (date_string, "%I:%M"); //do something with date_string; I may be missing a cast or something (emailware), but I think that's how it'd work. However, it seems really awkward that strftime() is bound like that, as it's not at all what a Vala programmer would expect. May just be an artifact of ongoing work for getting arrays working right though. Maybe Vala should ship a new Time() class that makes this less awkward to work with? And/or we could scream at the GLib guys to make a new (portable) GTime class for GLib 3.0... Maybe you could hack something around GDate for your needs? -A.
