The time of Arrival is most often reckoned as the moment the mass-driver engines cut out at the end of the last burn, putting the colony ship into stable orbit around Saturn.

Some minorities of saturnites reckon the moment of Arrival differently: Because the ship's flight was being monitored so closely, all of the accepted times of Arrival are known with high accuracy.
 * Completion of the insertion burn that put the colony ship in orbit around Enceladus, some weeks after attaining orbit around Saturn.
 * A point approximately two-thirds through the second burn, which irrevocably placed the ship within Saturn's gravitational influence.
 * The moment the ship first began to feel Saturn's gravitational influence, several titans before the first insertion burn.
