Inconsistencies are either within a series or between a series and its attempted chronologisation. Nicholas van Rijn says he was born too late to attend the Council of Hiawatha. (1) The passage summarising the Council ends:
"But when a century had passed -" (2)
This implies that van Rijn discussed the Council a century after it. The Chronology of Technic Civilization tells us that:
van Rijn was born in 2376;
the Council met in 2400;
the crisis that caused van Rijn to discuss the Council occurred in 2456. (3)
the Council met in 2400;
the crisis that caused van Rijn to discuss the Council occurred in 2456. (3)
Thus again (see here) the text of a future history implies a longer period of time than the accompanying chronology.
