This question already has an answer here:
Both transactions and blocks have a
time field when you use Bitcoin's
gettransaction methods. The API method list defines the transaction time as " time the transaction occurred".
Is this the time the transaction or block arrived at my client? Or is this time defined by the sender of the transaction or block?
I tried to encode a transaction to a raw transaction and decode it again afterwards, but the
lock_time property is set to
0 when I do this.
The reason for this question is that I want to make sure that when you check all transactions twice, all new ones of the second check have a time value higher than the highest one of the first check.
