Find bitcoin address based on transaction times, how?

Here's an example of electrum wallet transaction times - https://i.imgur.com/1m1fIMQ.png

What's the easiest way to search for the public address of those transactions, based on time and date (and the beginning of the address).

*Tried https://blockchair.com/ haven't managed to filter dates and time.

The time that you see on Electrum or other wallets are displayed as per the time relayed to them. This means that each block explorers will have a fairly significant disparity in the time received. When you're talking about a TPS of 7 tx/s, you'd be looking at a few hundred transactions to filter out. You can use blockchair to filter the unconfirmed transactions though: https://blockchair.com/bitcoin/mempool/transactions?s=time(asc)#, https://blockchair.com/bitcoin/transactions?s=time(asc)#.

I would take the above results with a grain of salt, some blockexplorers doesn't even see the transactions until it's mined. It could have been made days ago but the blockexplorer can only show the timings based on the time that the block was mined.

I agree with what ranochigo said. Every explorer/wallet/service will show a different time. As an example I used the last Roobet signature payment and checked the transaction hash on multiple explorers. I used blockchair.com, blockstream.info, and blockchain.com.

You can check the hash and the times these explorers show below:

Blockchair - 01:22
Blockstream - 02:22
Blockchain - 02:06

The timestamps between Blockchair and Blockstream show a one hour difference, but that can be because they use different time zones, and the hash was actually relayed to them around the same time. But you can see the obvious difference to what Blockchain has.

The best way to distinguish transactions is using one new address for every client (if you are buying/selling something). That way you can't make mistakes who regarding who sent what and where.

Other than the difference in the timezone, Blockchain.com is displaying the actual time that it was relayed. Both Blockchair and Blockstream are displaying the time whereby the block that includes the transaction was mined. I think both of the other blockexplorers changes the timestamp to the block's timestamp after it gets mined and discards the relayed time.

From what I know there is no block explorer website that has the ability to filter out transactions of an address by date but the good thing is transactions are arranged in a manner where you won't need to filter them out since the newest transactions are show first. So if you want to look at transactions that happened at an older date you can just navigate your way on looking at the other pages for that address to see on the transactions that happened on the date you are looking for.

Thanks.

Another question - how can I search for ALL the transactions with a specific amount that was sent (example - 0.17002205 BTC, 23rd August 2014).

You can use Blockchair's interactive search feature by going to https://blockchair.com/bitcoin/transactions , scroll down to "Monetary", and select the filter button to the right of "Input Total (BTC)". Then there will be a box that lets you fill in the equal value, but there are also boxes for lowest and highest amounts of BTC. It even lets you filter transactions by USD amount and date/time all at once, so it's a really useful search tool.
