        This may raise ValueError, if the timestamp is out of the range of
        values supported by the platform C localtime() function. It's common
        for this to be restricted to years from 1970 through 2038. Note that
        on non-POSIX systems that include leap seconds in their notion of a
        timestamp, leap seconds are ignored by fromtimestamp().
