The clocks that heard it first
The MC ledger keeps time by counting pulses from a dozen pulsars, on every world at once. This is that count, live, and the timing residuals where the beacon from Ross 128 b keeps showing up.

What doesn't fit the clock
A residual is the difference between when a pulse arrives and when the clock says it should. Normally it is noise. Every 9 h 41 m the beacon passes and every node sees the same wobble, each a little later than the last.

The array
Pulses counted since 2219-01-01
Twelve real pulsars and their real periods. The slow ones blink at their true rate.
| Pulsar | Period | Rate | Pulses |
|---|
Periods from the ATNF Pulsar Catalogue, rounded. The count starts at phase zero on 2219-01-01 and ignores spin-down and the observer's motion, so it is a story clock, not an ephemeris. The beacon's 9 h 41 m repeat is part of the story. The full record of the signal.
