But if you don't know where you are, you still don't know how old this
timestamp is. You only know what the time was when the message was sent.

If you receive this message on Alpha Centauri, your clock is still 4,5
years slow. Fortunately the odds are you won't accidentally end up there
without knowing, so the inaccuracy might be within your limits.
