1. A communication method comprising the steps of: at an energy management system on-board a vehicle, communicating with an off-board vehicle scheduling system for the establishment of a mutual clock; andat the energy management system, performing a first set of operations based on the mutual clock
1. A communication method comprising the steps of: at an energy management system on-board a vehicle, communicating with an off-board vehicle scheduling system for the establishment of a mutual clock; andat the energy management system, performing a first set of operations based on the mutual clock and performing a different, second set of operations based on a first clock of the energy management system, wherein the first clock is different from the mutual clock. 2. The method according to claim 1, further comprising the step of: communicating with the vehicle scheduling system for the establishment of the mutual clock to be used by both the energy management system and the vehicle scheduling system. 3. The method according to claim 1, wherein: the vehicle scheduling system includes a second clock; andwherein the mutual clock is one of the first clock and the second clock. 4. The method according to claim 1, wherein: the mutual clock is one of a GPS clock or a NTP clock. 5. The method according to claim 1, wherein: the energy management system includes a vehicle control system on-board the vehicle; andthe vehicle scheduling system includes an off-board positive train control system. 6. The method according to claim 1, wherein: the energy management system includes a vehicle control system on-board the vehicle; andthe vehicle scheduling system includes an off-board vehicle safety system. 7. A communication method comprising the steps of: at a first system, communicating with a second system for the establishment of a mutual clock to be utilized by both the first system and the second system; andat the first system, performing a first set of operations based on the mutual clock and performing a different, second set of operations based on a first clock of the first system, wherein the first clock is different from the mutual clock. 8. The method according to claim 7, further comprising the step of: at the second system, performing a different, third set of operations based on the mutual clock. 9. The method according to claim 7, wherein: the mutual clock is a GPS clock. 10. The method according to claim 7, wherein: the first system is an energy management system on-board a rail vehicle; andthe second system is an off-board vehicle scheduling system. 11. The method according to claim 7, wherein: the first system is integrated with a first rail vehicle; andthe second system is integrated with a second rail vehicle, the first and second rail vehicles being in the same consist. 12. The method according to claim 11, wherein: the first system is a first distributed power system on-board the first rail vehicle; andthe second system is a second distributed power system on-board the second rail vehicle. 13. A vehicle control system comprising: a first system for use with a first vehicle, the first system having an on-board first clock;wherein the first system is configured to communicate with a second system, the second system having a second clock;wherein the first system is configured to establish a mutual clock with the second system, the mutual clock being different than the first clock; andwherein the first system is configured to perform a first set of operations based on the mutual clock and a second set of operations based on the first clock. 14. A system for rail vehicle time synchronization, comprising: a first system for use with a first rail vehicle, the first system having an on-board first clock; anda second system in communication with the first system, the second system having a second clock;wherein the first and second systems are configured to establish a mutual clock, the mutual clock being different than the first clock; andwherein the first system is configured to perform a first set of operations based on the mutual clock and a second set of operations based on the first clock. 15. The system of claim 14, further comprising: an event recorder on-board for use with the first rail vehicle;wherein the second set of operations includes recording events utilizing the event recorder, the events including one or more of speed, direction of travel, distance, throttle position, operation of brakes, status of headlights and marker lights, or operation of horn. 16. The system of claim 14, wherein: the mutual clock is a GPS clock. 17. The system of claim 14, wherein: the first system is an energy management system on-board the first rail vehicle; andthe second system is an off-board vehicle scheduling system. 18. The system of claim 14, wherein: the second system is integrated with a second rail vehicle, the first and second rail vehicles being in the same consist.
