Locktime attribute of Bitcoin learning-transaction

Locktime, also known as nlocktime from the variable name used on the reference client, defines the earliest time that a TR Ansaction is valid and can being relayed on the network or added to the block chain. It is set to zero in the transactions to indicate immediate propagation and execution. If Locktime is nonzero and below of million, it is interpreted as a block height, meaning the transaction was not valid an D is not a relayed or included in the blockchain prior to the specified block height. If It is above-million, it is interpreted as a Unix Epoch timestamp (seconds since jan-1-1970) and the transaction are Not valid prior to the specified time. Transactions with Locktime specifying a future block or time must being held by the originating system and transmitted to the Bitcoin network only after they become valid. The use of locktime are equivalent to postdating a paper check.

Locktime, also known as Nlocktime, defines the earliest time, and this transaction can be sent to the Bitcoin network only after this earliest time. is usually set to 0, which means that transaction is sent to the Bitcoin network as soon as it is created. If the nlocktime time is between 1 and 500 million, then the transaction will only be added to chunks with a block height greater than or equal to Nlocktime. If the value of Nlocktime is more than 500 million, it is calculated from January 01, 1970, plus a point in time after nlocktime seconds, and if transaction is created earlier than that point in time, the transaction will not be sent to the Bitcoin network. The transaction with locktime indicates that the transactions will be verified and sent to the Bitcoin network in a future block or a future point in time. ...
