Field notes
The guide describes estimating a server's time by repeatedly requesting its response timestamp and targeting the moment its displayed second changes. A measurement is said to take about five seconds, with an error range shown alongside the result. The page also offers an iframe clock for blogs and café pages, plus a warning that sites with multiple servers may not open on the same server whose time was measured.
