The first file on the public clock calibration began with clock calibration cards and service boards that use the signal. The city then checked the source, heard affected residents and sent a second office to repeat the count.
The current Year third, long dusk window 3 file records 31 service boards with a matching calibration date; the previous window records 29. The longer sequence makes the change visible, while each count remains tied to its own dates.
A turning point was the observation that the clock is adjusted while transit notices remain posted. It narrowed the discussion from a general claim to a question about how the rule works at the site.
The clock keeper trusts the calibration card. Residents rely on the displayed signal at the route entrance. The shared record is larger than it was at the start, although the parties still assign it different weight.
Residents and workers submit accounts before the hearing closes. The Year third, long dusk window 3 file remains open for its scheduled decision. The clock office will post the calibration window on every connected service board.
