Plz Can we get the exact time of a payment first confirmation ?

example: i need to know when a payments was confirmed .

like this payment : https://blockchain.info/fr/tx/d4ea8f52195e82c68e9ca3e21986db67b904fe01d1156b69e60e95394b0b6c9c

can you know when it was confirmed (exactly).

Thank you .

The exact time of your first confirmation is the block generation time of which has included your transaction.
Because I do see may transactions remind unconfirmed for some time, it had got it's first confirmation once it got included into a block. So the first confirmation time must be exact equal to the included block generation time.

Yet the block generation time is often manipulated by miners in order to find the hash for a valid block. They dont even have to be in order[1,2]. Thus the exact time for the first confirmation is only known to the miner that finds the block.

Code:

145044: 2011-09-12 15:46:39     
145045: 2011-09-12 16:05:07 
145046: 2011-09-12 16:00:05 // ~5 minutes before prior block
145047: 2011-09-12 15:53:36 // ~7 & ~12 minutes before 2 prior blocks
145048: 2011-09-12 16:04:06 // after 2 prior blocks but still before 145045

Just pay the appropriate fee to begin with and you'll unlikely end up with any more "old transaction".

Never ending parties are what Im into.

Opened this thread thinking nothing could really be done to find the exact time but actually learned some stuff.
Thanks Agentofcoin for that little blip,I will try to use that next time I make a transaction.

Think one of the biggest lessons I ever learned was to make sure you have miners fee activated on your phone or you could be waiting hours.
Was waiting at a atm one of the first times to make a withdrawal and 45 minutes had gone by and I was confused. Went into their office and they checked my phone as I stood there like a moron and they found I had not clicked the bigger fee. So once that was clicked I made another transaction for the same amount and boom both transactions came through at the same time. Now I am wondering if you could always do that or if that was just fluke that both transactions where pushed through at the same time?
My thinking is not to be cheap but to help push a old transaction in the future if I some how make that same mistake.

Yes.
When you click that link, on that page, its states to the left which block it was included in.
That block would be your first confirmation.
If you find out what time that block was "found and received", then you would know the time of your first confirmation.

According to that site: 2015-09-18 01:37:30. now you need to figure out their time zone in relation to yours.
I do not know what timezone Blockchain.info is using.

Eh, OP is asking for the exact time when the transaction was first confirmed. Blockchain.info would only give you a rough estimate of when it was included in a block (2015-09-18 01:37:30 + 5 minutes, see the + 5 minutes in it for margin of error). Oh, and blockchain.info uses UTC.

There is no way to know when it was "exactly".
All miners are using different time stamps when they report their found block.
The only way to know the "exact/actual/factual" time is probably to be the miner that found it.

The time that blockchain.info shows is what the miner reported the time to be. (whether exact or not).

Also, i think when Blockchain.info says (+5) after the time,
it is actually saying that that tx was confirmed in that block, 5 minutes, after being relayed.
Meaning, it took five minutes for the tx to get 1 confirmation.

So to conclude, the + n minutes in blockchain tells the user how many minutes it took the transaction to obtain one confirmation? I see now. Just looked up on different transactions too, some has +11 mins., +6 mins., and so on.

Yes. But I think, when it comes to this, Blockchain.info is really only reporting what the miner claims.
So if i send a tx now, and a miner finds a block in 5 mins,
but reports it found it in 4 mins, then it will say I waited 4 mins, even though it was really 5 mins.

And if I am correct, then you can never really know the "true/exact" time the block was found, unless you physically mined it.

P.S. i like how we have had this conversation, but the OP hasn't appeared again yet. lol.

The time it was first confirmed by the network? I don't think it is possible to know what the exact time is, but you can get a good hint by looking at the time the transaction was first picked up by the network and the fee that was included on it.

No i want to know the exact time and i think i found a way witch is by Keep watching The address useing a simple Get script (Js Or Php).

What do u think ? will works ?
