For the avoidance of doubt, such blocks must still comply with existing Median-Time-Past nTime restrictions." The originally proposed rule has been adapted to allow for a delta of 7200 seconds instead of only 600 seconds to allow honest miners to mine at the current time even if an attacking miner has postdated the timestamp up to the allowed 2 hours in the previous block. +To protect against the time warp attack, the following rule proposed as part of The Great Consensus Cleanuphttps://github.com/TheBlueMatt/bips/blob/cleanup-softfork/bip-XXXX.mediawiki is enforced: "The nTime field of each block whose height, mod 2016, is 0 must be greater than or equal to the nTime field of the immediately prior block minus 600.
