Is that Earth-time or Space-time?

A recent visitor to Rocket Ship Foundation was conducting an examination of one of our displays of cockpit layout. On seeing the clock she expressed surprise, before asking: Does the clock show earth or space time? What an interesting question. The answer is: on Earth the clock points to time as recognised here. When in Space the clock will tick to the beat of the heavens, as noted by Mr Einstein. We do hope that answers your question.

Is that Spacetime or Earthtime

A visitor points to the clock and asks a very fundamental question about space and space-time.
