- It uses Marzullo's algorithm to find the overlap among agreeing time-source intervals and labels the displayed error bound as a hard limit.
Field notes
The page shows source status, round-trip times, consensus offset, and an error bound, and explains how agreeing source intervals determine the displayed time. Its camera-drift workflow asks users to film the clock and compare a frame's visible digits with footage timecode or a file timestamp, then repeat later in the recording. The page says display latency is partly compensated, while screen and camera delays remain outside the stated error bound.
