Timestamps are not accurate in bitcoin. You can place any timestamp you like in a range which is defined as 2 hours before or after the median time of the last ten blocks.
If I remember correctly 😅

Something like that, but mempools.space should be calculating block time, and time since last block, with their own node's clock, no?
They could, but they just show the timestamp of the block.
The “time since last block” is always relative to a specific node because not all nodes receive a new block at the same time.
It’s possible that your node receives a new block half a minute later than mempool.space or the other way around. Or a node can receive block x+1 before block x
This time problem is the reason why we have a blockchain. It’s not possible to say which order of events is the correct one when it comes to decentralized networks. It’s a extremely complex topic
Does that explain why nostr:npub1ypznd87pzkcn352r37vd8s5ez6vxe877dwpq8alls6vlp7hwrjfspp27hc screenshot of mempool shows blocks in order with strange "time since" between them?
Exactly
