I wonder how I can find this is 22 second block. Thanks.
You'd have to be running a bitcoin node connected to the fibre relay to get a 'close to accurate' idea:Block! by jimmy

That was a short 22 second block and even faster - confirmed 8 seconds later!

- look in the debug.log for the previous block (475569) arrival time, and then our block (475570) arrival time and then the next block (475571) arrival time.
22 seconds from 69 to 70, then 8 seconds from 70 to 71.
