Localtime to Localtime_s

[CDavis]

I'm having issues converting my local time. Can anyone tell me what I'm doing wrong

My code when I got the localtime error

time_t tm = m_Flight.dateStamp;
struct tm t = *localtime(&tm);
char buf[80];
strftime(buf, sizeof(buf), "%a, %d %b %Y %H: %M: %S", &t);
return string(buf);

I tried the following

time_t tm = m_Flight.dateStamp;
struct tm t;
localtime_s(&tm, &t);
char buf[80];
strftime(buf, sizeof(buf), "%a, %d %b %Y %H: %M: %S", &t);
return string(buf);

What sort of error are you getting?
