Transaction.setLockTime介绍

[英]Transactions can have an associated lock time, specified either as a block height or in seconds since the UNIX epoch. A transaction is not allowed to be confirmed by miners until the lock time is reached, and since Bitcoin 0.8+ a transaction that did not end its lock period (non final) is considered to be non standard and won't be relayed or included in the memory pool either.
[中]事务可以有一个关联的锁定时间，可以指定为块高度，也可以指定自UNIX纪元以来的秒数。在达到锁定时间之前，矿工不允许确认交易，而且由于比特币0.8+未结束锁定期（非最终）的交易被视为非标准交易，也不会被中继或包含在内存池中。
