It=E2=80=99s expected. It=E2=80=99s not possible to travel so far back. T= he zero for time-traveling is the introduction of =E2=80=9Cinferiors=E2=80=9D mechanism= around 2019. Well, since the question is recurrent, I agree that: 1. the manual needs to be improved; 2. the command =E2=80=9Cguix time-machine=E2=80=9D should raise a gentle e= rror when the specification is unreachable.
