   That's not technically correct, as it requires a signalling period and a fallow period (both 2016 blocks) after the start time (unless you assume 4032 blocks can be mined within 24 hours).

   Oh, indeed. What was I thinking. I'll edit.

   Nov 15th is the earliest date that signalling can start. Earliest activation is likely to be ~28 days/4032 blocks from the next retarget after 15th Nov (estimated to be 20th Nov). I would hazard to be so specific.

   Still not technically correct. Tracking will start from the first retarget after the 15th.
