Just as Poul Anderson's Technic History extends from post-Chaos recovery to the period of the Commonalty, the Time Patrol history extends from the Academy in the Oligocene period through other past periods visited by Everard and future periods guarded by agents like Komozino to the civilization of the Danellians.
The most remarkable fact that we learn about Komozino is that she might have spent years of lifespan in research and preparation between learning of the temporal upheaval and contacting Everard. Dealing with the upheaval is a matter of urgency but a time traveller can spend years on something urgent.
