1. A method for setting a date and time in a medical device to a time zone in which the medical device is located, the medical device having a microcontroller responsive to blood glucose values and connected to a wireless receiver, the method comprising:
- scanning a predetermined range of frequency values with the wireless receiver, in which at least one frequency value has a wireless signal, the wireless signal having a current date and time information encoded therein;
determining a frequency value having a signal strength greater than as compared to any other frequency values in the predetermined range;
setting the wireless receiver to the determined frequency value; and
synchronizing a clock in the medical device to the current date and time encoded at the determined frequency value.
