Directory authorities on master are causing clock skew warns on every reachability test

A growing number of relay operators started complaining tonight of lines like
Sep 21 05:22:01.021 [Warning] Received NETINFO cell with skewed time from server at 22.214.171.124:9090. It seems that our clock is ahead by 15969 days, 3 hours, 22 minutes, or that theirs is behind. Tor requires an accurate clock to work: please check your time and date settings.
That's 1970. Mike maintains his clock is correct. And also he upgraded to git master recently.
In parallel, git commit 1d0ba9 does
- /* Timestamp. */ - set_uint32(cell.payload, htonl((uint32_t)now)); + /* Timestamp, if we're a relay. */ + if (! conn->handshake_state->started_here) + set_uint32(cell.payload, htonl((uint32_t)now));
That means every outgoing connection from a directory authority puts a time of 0 in the netinfo cell during its handshake. And relays are programmed to log_warn if they get told a time from an authority that disagrees with their opinion about what time it is.
