wherein after an electric power supply to the information processing apparatus is started, a first case arises where the calculation section calculates the sunset time based on the position information stored by the position information storage section before the position information becomes acquirable from the position information acquisition section;
wherein after the first case arises, when the position information becomes acquirable from the positional information acquisition section, the calculation section determines a use validity of the position information stored by the position information storage section, based on the position information newly acquired from the position information acquisition section;
wherein when the use validity is affirmatively determined, the calculation section regards the sunset time calculated when it is determined that the head light of the vehicle is changed from the light-off state to the light-on state as being valid; and
wherein when the use validity is negatively determined, the calculation section re-calculates the sunset time based on the position information newly acquired from the position information acquisition section and the calculation section substitutes the re-calculated sunset time for the sunset time calculated when it is determined that the head light of the vehicle is changed from the light-off state to the light-on state.
5. The information processing apparatus according to claim 1,
wherein a second case arises where the calculation section is unable to calculate the sunset time at the lighting-on time of the head light when it is determined that the head light of the vehicle is changed from the light-off state to the light-on state;
wherein after the second case arises, the calculation section calculates a sunset time based on position information, which is newly acquired from the position information acquisition section before a predetermined time elapses since the lighting-on time or before a predetermined distance is traveled by the vehicle since the lighting-on time; and
wherein the evaluation storage section stores the lighting-on time and the sunset time calculated by the calculation section, in association with each other.
6. The information processing apparatus according to claim 1, further comprising:
a first evaluation section configured to evaluate a lighting-on time of the head light based on the lighting-on time and the sunset time which are stored by the evaluation information storage section.
7. The information processing apparatus according to claim 1, further comprising:
a day and night determination section configured to determine whether a present time is daytime or nighttime based on a newest sunset time calculated by the calculation section;
an in-tunnel light information storage section configured to store a number of tunnels the vehicle traveled and a number of in-tunnel lighting-on undergone by the head light of the vehicle in tunnels; and
a second evaluation section configured to evaluate lighting-on of the head light in tunnels based on the number of tunnels and the number of in-tunnel lighting-on of the head light.
8. The information processing apparatus according to claim 1, further comprising:
an offset time change section configured, when it is determines that the vehicle passed a border of a time zone based on a present position of the vehicle specified based on the position information acquired from the position information acquisition section, to amend an offset time, which is based on Greenwich Mean Time, the offset time being used when calculating the lighting-on time and the sunset time.
