1. A timing system for supporting a determination of a time of passing of a monitored detection point by a participant in an event having an RFID tag with a participant identifier associated with a unique participant identifier number, the system comprising:

  • a timing system server having a processor, a communication interface, a non-transitory memory, computer executable instructions and a first interface to interface with an RFID tag reader positioned proximate to the monitored detection point, a second interface to interface with a portable handheld device positioned at a spaced apart distance from the monitored detection point, and a third interface to interface with a participant/event reporting system, the timing system configured to;

    store a current geographic location of at least one of the RFID tag reader and the monitored detection point the memory;

    receive over the first interface one or more RFID tag reads of the RFID tag when the RFID tag is in proximity to the RFID tag reader, each received RFID tag read including the RFID participant identifier number and the RFID tag read times by the RFID tag reader;

    receive over the second interface a handheld device participant identifier number, a handheld device time, and a current geographic location of the handheld device,correlate the received RFID participant identifier number with the received handheld device participant identifier number to determine the participant identifier number;

    store the received RFID tag read times and the received handheld device time in the memory associated with the correlated participant identifier number;

    store the received current geographic location of the handheld device;

    compare the received RFID tag read times to the handheld device time;

    determine that the received RFID tag read times are not usable as the time of passing of the monitored detection point by the participant;

    determine a delta time from the difference in the stored current geographic location of the RFID tag reader and the received current geographic location of the handheld device;

    calculate an adjusted time for the participant identifier number from the received and stored handheld device time and the determined delta time;

    store the calculated adjusted time as a time of passing of the detection point for the participant; and

    transmit over the third interface to the participant/event reporting system the participant identifier number and the calculated adjusted time as the time of passing of the participant having the participant identifier number.
