Following the BIP9 recommendation [1] to set the versionbits start time a month in the future and discussion in the last IRC meeting [2], I propose we set BIP 141's start time to November 15, 2016, 0:00 UTC (unix time 1479168000). Note that this is just a lower bound on the time when the versionbits signalling can begin. Activation on the network requires: (1) This date to pass (2) A full retarget window of 2016 blocks with 95% signalling the version bit (bit 1 for BIP141) (3) A fallow period consisting of another 2016 blocks.
