Understanding transactions

[odr_express]

Hi, I have trouble understanding a few transactions and what they mean. I hope someone could help me understand them. Here is the table:

Date	Type	Address	Amount (BTC)	ID
2013-04-17T17:31:35,000	Received with	1CXarVzTtgCR5NhLvX6AhQxvKE9RXRtz73	0.01000631	1807aefc637b22a043c0524fa1477e32d4b21196d1b6ce043dcbc5cd0106472b
2013-04-17T17:31:35,000	Sent to	1CXarVzTtgCR5NhLvX6AhQxvKE9RXRtz73	-0.01000631	1807aefc637b22a043c0524fa1477e32d4b21196d1b6ce043dcbc5cd0106472b

• The timestamp is exactly the same for all for rows, but there are two transactions. Is that normal?
• The amount of 0.01000631 BTC is sent the received from the same address. Does that mean it is the split/rest value of the address that is returned to the sender?
• How many BTC was actually sent? 9, 7, or 9+7=16? Is it possible to understand this from the transactions?

Any hints are much appreciated.

It's a bit confused, honestly. What wallet exactly are you using?

Anyway, if you can't understand this transaction, you better use some Bitcoin explorer to understand the transaction sample on mempool.space below

The timestamp is exactly the same for all for rows, but there are two transactions. Is that normal?

Honestly, I am confused at first glance, but it seems that I understand them now.
The timestamp is the same because it's a whole transaction associated with this TXID "1807aefc637b22a043c0524fa1477e32d4b21196d1b6ce043dcbc5cd0106472b".
The only weird part is the last part which this one below

2013-04-17T17:31:35,000	Sent to	1FrFG1KxNYf585noYBQkvztQ86sFm5JoaD	-9.00000000	998bcb58e08b174674f868b3fe1f172856984b527c2c414a7c34185d21d7d1e9

Maybe you created these transaction at the same time that is why they have the same timestamp.

The amount of 0.01000631 BTC is sent the received from the same address. Does that mean it is the split/rest value of the address that is returned to the sender?[/li][/list]

That is the change amount sent back to your wallet.  It was split from the amount(7 btc) you sent to 13PSaXZaRNPyxcCetHTQxUzsiX4y7MYv7H

How many BTC was actually sent? 9, 7, or 9+7=16? Is it possible to understand this from the transactions?

From this transaction: 1807aefc637b22a043c0524fa1477e32d4b21196d1b6ce043dcbc5cd0106472b
You sent 7 BTC

While in this transaction: 998bcb58e08b174674f868b3fe1f172856984b527c2c414a7c34185d21d7d1e9
You sent 9 BTC but according to the transaction it also has a change sent to 1BcoSuLEs3sGcLVN9D87GMoTAW6LFKef42 around 0.01000239 BTC.

Meaning your calculation is right.

I only think that this transaction was created in an scheduled manner that's why they have the same timestamp. The rest you explain i guess were alright ad those first 3 mentioned by OP where came from the same txid.

• The timestamp is exactly the same for all for rows, but there are two transactions. Is that normal?

The data on the first three rows are for the same transaction since they all have the same transaction id.
Different transactions having the same timestamp is completely normal. It simply means they were included in the same block. It’s block 231833 and it contains 641 transactions. All of them will have the same timestamp.

• The amount of 0.01000631 BTC is sent the received from the same address. Does that mean it is the split/rest value of the address that is returned to the sender?

Yes. It’s a change address but the transaction has many other inputs.

• How many BTC was actually sent? 9, 7, or 9+7=16? Is it possible to understand this from the transactions?

Yes.
7 btc were sent to the 13PSa.. address through the first transaction and 9 btc were sent to the 1FRF.. address through the second transaction.

Thank you all! Yes, it makes sense if it is the block time! I was wondering why this was happening at the exact same time, because those were not scheduled or anything.

This is a transaction CSV export from an old Bitcoin-qt wallet.

Thanks again for your help!

The reason why you see different transactions having the same timestamp is because what matters is the block time.

I saw that Oc have explained it briefly. I recommend you to look at the block explorer and get used to it.

       
You will learn how the blockchain works, what dust transactions are; why sometimes a btc goes to a wallet but remainder goes somewhere else.
       
       
Learning is fun.
