Adrian Veil opens clock calibration cards and service boards that use the signal at the civic clock at South Arch. Before anyone changes a mark, the crew checks the clock is adjusted while transit notices remain posted. The long dusk period sets the pace of the work.
The page holds 67 service boards with a matching calibration date. Adrian Veil reads the preceding count, 67, before the next line is entered. A number without a date would not tell the next crew what changed.
The clock keeper trusts the calibration card. Residents rely on the displayed signal at the route entrance. Here the difference is visible between the posted rule and the route, service or shift just beyond the door.
The board publishes options with the people and dates affected stated clearly. The Year first, long dusk window 3 file remains open for its scheduled decision. The clock office will post the calibration window on every connected service board.
The shift closes with the source page attached to the board. The next file uses a new date and scope.
