0.3.4 authorities will post votes that other authorities on 0.3.3 or 0.3.4 consider too old:

$ grep -r "21:05:33" . | grep -v -e info -e debug | sort -k 3

./000a/notice.log:Aug 29 21:05:33.835 [notice] Bootstrapped 80%: Connecting to the Tor network

But I've also seen 0.3.3 authorities reject their own votes for this reason.
