My bad.... Here was the one that caught my eye on a quick scan:
// src/boinc-6.12.38/api/boinc_api.cpp, line 217
if (localtime_s(&tm, &x) == EINVAL) {
...
}
Also, strftime() ignores its return value. The function returns 0 on
failure or 'N >= sizefo(buf)' on truncation (where N is the number of
bytes written)..
