        The function receives a pointer to the timestamp to convert as its
        first argument (<code class="literal">ts</code>), a pointer to the output buffer
        (<code class="literal">output</code>), the maximal length that has been allocated for
        the output buffer (<code class="literal">str_len</code>) and the format mask to
