How certain are you that there weren't multiple blocks added to the client's blockchain between the initial buliding of the transaction and when it was eventually included in a block?
Not sure if this is what you mean but the txn was initiated only a few mins prior to appearing in the next block so I'd imagine the age is at most 1 or 2 out. The txn was added to the same
block 68950 as the previous txn (
f8187d) initiated from the same client.
