Hello, Netizens !

I am wandering what is the average human ability to visually compare two 
clocks ? Let say I have XClock application running on one machine 
(stratum 1 NTP) and I have my project clock close by. And I would like 
to match the reading. If I'll see the difference, which range it will be 
? 100ms or so ?
I also tried to use my ears (CHU radio signals and clock display, NRC 
phone line). However NRC "Talking Clock" could be routed via Satelite 
which will compromise the "reading" a little bit. Thanks !
