+       The strftime() function returns the number of bytes placed in the array s, not including the  terminating  null  byte,  provided  the
+       string,  including  the  terminating  null  byte,  fits.  Otherwise, it returns 0, and the contents of the array is undefined.  (This
+       behavior applies since at least libc 4.4.4; very old versions of libc, such as libc 4.4.1, would return max  if  the  array  was  too
+       small.)
+
+       Note that the return value 0 does not necessarily indicate an error; for example, in many locales %p yields an empty string.
