Given that:
- According to the white and yellow paper a block's timestamp must be bigger than the parent's.
- According to the white paper a block's timestamp can be within 15 min of the parent blocktimeblock's timestamp can be within 15 min of the parent blocktime.
Would that imply that if a differential block time of 14 min occurs,
- the next winning miner has to either fake a timestamp, and this potentially could lead to the blockchain running faster and faster into the future,
- or wait until his Unix time catches up.
Is this true? Is there a reason why empirically it never happened?
