Hi @criptraders, glad that you tried to read my post.
It's about how to deal with "Time" on smart contracts. Since we cannot trust timestamps provided by nodes, the only way to get timestamp of a transaction is to get the timestamp of the block containing the transaction.
So I provided a sample code about how to implement this in neo-python. If you're interested in smart contract development, I encourage you to look into it, it's easy to use, and I think NEO does have several advantages over Ethereum.
