1. A method of determining time compensation in a V2X system, the method comprising:
receiving at a transceiver device of a vehicle a plurality of electronic messages from a plurality of senders;
for each sender of the plurality of senders, individually determining a time compensation offset based upon a difference between timestamps in messages received from each sender and an ego time of the transceiver device;
applying the time compensation offset determined for each sender to each timestamp of each message of each sender to create a modified timestamp for each message from each sender;
transmitting each message including each modified timestamp to at least one vehicle application of the vehicle and wherein the application processes each message according to each modified timestamp to selectively perform an action.
