How Does a Block’s Timestamp Affect Its Acceptance by the Network?
A block's timestamp must be greater than the median timestamp of the previous 11 blocks and not be too far into the future (typically no more than two hours ahead of the node's local time). This prevents miners from manipulating the time to affect the difficulty adjustment or create blocks that appear to have been mined in the future, maintaining the chronological integrity of the chain.
