In other words, it is determined whether the date / time information of the battery pack 20 is the latest date / time information obtained from the charger 30 (ST131).

  When the elapsed time of the date / time information from the battery pack 20 is within a predetermined time, the arithmetic processing unit 15 of the electronic device 10 updates the date / time information of the time measuring unit 13 to the date / time information received from the battery pack 20, and the time measuring unit 13. Generates a new device date / time accuracy information when the timing process is started based on the date / time information (ST131 → ST132).

  The arithmetic processing unit 15 of the electronic device 10 sets the date and time information updated by the time measuring unit 13 as the latest date and time information in the device, and displays the set date and time information on the display unit 16 (ST132 → ST115 → end).

  When the elapsed time of the date / time information from the battery pack 20 exceeds a certain time, the arithmetic processing unit 15 of the electronic device 10 updates the date / time information of the time measuring unit 13 to the date / time information received from the battery pack 20, and 13 starts the timing process.

  The arithmetic processing unit 15 of the electronic device 10 sets the date and time information updated by the time measuring unit 13 in the device, and displays message information for prompting acquisition of the latest date and time information on the display unit 16 (ST131 → ST133 → end). ).

  In addition, time difference information is stored in the memory 18 of the electronic device 10, and the time difference can be automatically corrected when the device is used in a country or region having a time difference.

  When correcting the time difference, the time difference is corrected based on the flowchart of FIG. 4 by turning on a function for correcting the time difference by the operation unit 17.

  When the date and time information of the time measuring unit 13 is updated in step ST114 of the flowchart of FIG. 3, the arithmetic processing unit 15 of the electronic device 10 next determines whether or not the time difference correction function for correcting the time difference is on. Is determined (ST200).

  When the time difference correction function is not on, the arithmetic processing unit 15 of the electronic device 10 sets the date and time information updated by the time measuring unit 13 to the device, and displays the set date and time information on the display unit 16 (ST200 → end).

  When the time difference correction function is on, the arithmetic processing unit 15 of the electronic device 10 reads the time difference information stored in the memory 18 and corrects the time difference of the date / time information updated by the time measuring unit 13 based on the read time difference information. The timekeeping unit 13 is updated to date and time information with the time difference corrected, and is set in the device and displayed on the display unit 16 (ST200 → ST210 → end).

  If data communication is not possible, data communication is not performed and the process ends (ST300 → END).

  When it is confirmed that data communication is possible, the arithmetic processing unit 35 of the charger 30 checks whether date / time information is set in the time measuring unit 33 (ST300 → ST310).

  When the date / time information is set in the timer unit 33 of the charger 30, the arithmetic processing unit 35 reads out the date / time information of the timer unit 33 and sends it to the battery pack 20.

The unit 22 generates new battery date and time accuracy information when the time measurement process is started (ST310 → ST320).

  On the other hand, when the date and time information is not set in the time measuring unit 33 of the charger 30, the arithmetic processing unit 35 receives the standard time signal by the receiving unit 36 or receives and receives the standard time information through the communication network. Standard radio waves or standard time information is sent to the arithmetic processing unit 35 (ST310 → ST315).

  The arithmetic processing unit 35 of the charger 30 generates date and time information based on the standard radio wave or standard time information received by the receiving unit 36 and sends the date and time information to the time measuring unit 33. The time measuring unit 33 starts the time measuring process and generates the time information. The date information is sent to the battery pack 20.

  When the arithmetic processing unit 24 of the battery pack 20 receives the date / time information sent from the charger 30 via the communication unit 23, the arithmetic processing unit 24 updates the date / time information of the time measuring unit 22 to the date / time information received from the charger 30. When the time counting process is started, unit 22 generates new battery date / time accuracy information (ST315 → ST320).

  Note that the battery date and time accuracy information generated by the timer unit 22 of the battery 20 is processed based on the flowchart shown in FIG.

  The arithmetic processing unit 24 of the battery 20 compares the time measurement start date / time included in the battery date / time accuracy information generated by the time measuring unit 22 with the date / time information processed by the time measuring unit 22 of the battery 20, At 22, the elapsed time of the date / time information being timed is calculated, and it is determined whether or not the elapsed time of the calculated date / time information has passed a predetermined time (ST 400).

  When the elapsed time of the date / time information exceeds a certain time, the arithmetic processing unit 24 of the battery 20 clears the battery date / time accuracy information of the time measuring unit 22 (ST400 → ST410 → end).

  When the elapsed time of the accuracy information is within a certain time, the arithmetic processing unit 24 of the battery 20 holds the battery date / time accuracy information currently in the time measuring unit 22 (ST400 → end).

  As described above, when the elapsed time of the date / time information exceeds a certain time, the battery date / time accuracy information of the timekeeping unit 22 is cleared to prevent the old and new battery date / time accuracy information from being set erroneously. The reliability of accuracy information is prevented from decreasing.
