to a time standard such as national institute of standards and technology in fort collins colo or any other known international time standard broadcasts atomic clock module 9 includes an antenna 22 for receiving the time code and contains components known in the art to convert the time code into a digital time code and decoding the time code bit stream to a form usable by cpu 4 in particular antenna 22 receives a radio frequency time code signal which is converted into a digital time and date code signal via cpu 4 cpu 4 therefore decodes the digital signal which is then output to any of the various components of monitor 2 including for example the glucose testing means glucose test strip input 10 and or bg resistance 11 display 8 voice processing i o 12 and i o output to doctor 14 to provide accurate time and date information which can then be used to create time and date stamps in connection with information inputted and or recorded into monitor 2 in one embodiment of the present invention monitor 2 is synchronized when monitor 2 is turned on automatically without the use of any key or button the individual is not.
