An electronic device has a first hand that displays a first time; a second hand that displays a second time; an indicator hand; a detection device that outputs a first time selection signal when it detects a first time selection operation of an input device, and outputs a second time selection signal when it detects a second time selection operation of the input device; a mode setter that sets a first time correction mode to correct the first time when the first time selection signal is received, and sets a second time correction mode to correct the second time when the second time selection signal is received; and a display controller that points the indicator hand to a position other than that of the second hand when the first time correction mode is set, and points the indicator hand to the second hand when the second time correction mode is set.

Embodiments of a digital clasp for a watch can include a watch having an analog watch face, a first watch band portion, a second watch band portion and an analog watch face. The digital clasp can include a clasp housing that includes a latch assembly configured for attachment to the first band portion and the second band portion, a digital display, and a circuit board associated with a controller.

Whether a bright state or a dark state is established is determined each time a motor is driven one step, based on a presence or absence of a passing of light through a detection hole disposed in a detection wheel that rotates associated with rotations of a hand wheel coupled with the motor. A switching position X is identified at which the dark state is switched to the bright state when the dark state is determined and thereafter the bright state is determined. A position one step after the identified switching position X is set to be a reference position X+1 of the hand wheel. The reference positions X+1 and X1 can thereby be set after a driving mechanism is assembled.

A timing device is disclosed which is for controlling electronic devices and which is mounted in a wall switch box. This timing device comprises at least one controller; at least one transceiver in communication with the controller; at least one interface; and at least one cover plate. This device can also include at least one key coupled to the cover plates for interacting with the interface when said cover plate is inserted onto said at least one interface.

A method for adjusting a clock on board a motor vehicle, the clock providing an actual time for functions of the vehicle, the vehicle connected via wireless communication to a data server, the method including: the server transmitting a sequence of consecutive actual-time values, separated from one another by a fixed time interval; the vehicle receiving the actual-time values shifted by an unknown and variable time of flight between transmission and reception; for each received actual-time value: calculating a difference between an actual-time value received at a given instant and an actual-time value received at a previous instant; calculating a discrepancy between the calculated difference and the fixed time interval; calculating a cumulative disparity, consisting in summing the discrepancy calculated for a time value received at one instant and a time value received at the previous instant; determining the actual time for adjusting the on-board clock according to the disparity.

Synchronization of precision timing signals maintained by multiple communication networks is described. A precision timing signal may be generated based on the change in state of a plurality of processors. Synchronization of the precision timing signals may be facilitated by a computing device monitoring at least two communication networks. The computing device may generate time offsets that are derived from the precision timing signals associated with each communication network. The time offsets may be communicated by the computing devices to remote devices communicatively coupled to the computing device via a first communication network.
