Neville, The Time of Arrival error for the millisecond pulsar J0437-4715 is about 11 nsec. This takes into account the location of the pulsar, the solar system's barycentre, the earth's (perturbed) orbit around that barycentre and not to mention the interstellar medium that the pulse has to travel

Re: [time-nuts] Time of death-Again

Surely astronomical events are rather rubbery. The distance between the celestial bodies is measured in Light Years, this must give uncertainties as the exact distances are varying all the time and the solution of the many bodied problem is probably chaotic, meaning that it may not be possible

Re: [time-nuts] 10811 EFC control

You need to understand that there is a +6.2V Zener diode reference connected to the cathode of the varactor. If you really want to minimize any perturbations of the oscillator by the tuning diode, you should operate up near +5V, so that the voltage across the varactor is minimized. Also, ideally,

If a far future observer was to make any sense of a date, quite a lot would have to be known about the culture, including how to read its markings. It would be impractical to carve a map of the sky showing the location of a stellar beacon on each tombstone, and then adding some number of rotations
