I mine a block and give it time x. The next block that I mine, I give time x+1 second. The block after that, x+2 seconds. And so on, for 2,015 blocks, up to x+2,014 seconds. The last block of the difficulty epoch I give a timestamp of the current time.
That last block is expected to violate the Future Block Time Rule (2 hours). Won't other nodes reject the block when the secretly mined chain gets published?
