1. A method of sensor history backfill for a local base device operable to communicate with a physiological sensor connected to a patient, the method comprising:
storing physiological readings at a memory device of the local base device as historic physiological readings, the physiological readings obtained by the physiological sensor at a predetermined interval;
receiving, at the local base device, a current physiological reading in a current reading message;
detecting, at the local base device, a record gap in the historic physiological readings between the current physiological reading and the historic physiological readings;
filling the record gap in the historic physiological readings with sensor physiological readings from the physiological sensor when the current reading message does not include the sensor physiological readings to fill the record gap, wherein the filling comprises:
retrieving, from the memory device, a Time Change marker that occurred during the record gap and was stored at the memory device of the local base device; and
adjusting a user clock associated with the historic physiological readings in the record gap on and after a time of the Time Change marker by a time change value associated with the Time Change marker; and
displaying, via a graphic user interface (GUI) of the local base device, the historic physiological readings with the record gap in the historic physiological readings filled with the sensor physiological readings from the physiological sensor.
