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. The remote devices may adjust locally maintained application clocks based on the time offset. The adjustment may synchronize the local application clock with the precision timing signal of a second communication network. In response, a remote device may communicatively couple with the second communication network.

An electronic timepiece includes a radio wave receiver, a communication unit, a memory and a processor. The radio wave receiver receives radio waves from positioning satellites. The communication unit communicates with an external device. The memory stores a program and predicted positional information on the positioning satellites. Based on the program stored in the memory, the processor shifts the timepiece between a normal operation state and a power saving state in which operation of the timepiece is restricted, depending on a status of the timepiece. In response to an elapsed time from a valid period of the predicted positional information exceeding a predetermined reference time during the power saving state, the processor causes the communication unit to receive updated data of the predicted positional information and other information from the external device when shifting the timepiece from the power saving state to the normal operation state.

Methods, systems, apparatuses, and computer program products are provided for enabling devices to determine the time zone in which they are located. A mobile device may receive location information from one or more sources. Based thereon, the current location of the mobile device may be determined in terms of latitude and longitude. The indication of the current location may be converted to an index value according to a Hilbert curve (or other space-filling curve), and the index value applied to a time zone index file to determine the local time zone. A time zone setting of the mobile device may be updated accordingly. Furthermore, geofencing may be used by the mobile device to detect movement towards and through a time zone boundary, leading to a new time zone determination being initiated.

Provided is an electronic timepiece that receives satellite signals more easily when satellite signal is received automatically. The electronic timepiece has a time display that displays time by the position indicated by a rotating first hand; a planar antenna that receives satellite signal transmitted wirelessly from a satellite; a receiver connected to the planar antenna; and a controller that operates the receiver when a specific condition is met. The planar antenna includes a dielectric substrate, and an antenna patch disposed to the substrate. The center of the patch antenna being disposed in the range between 6:00 and 11:00 on the time display.

A watch can include a mechanical watch, the mechanical watch having a mechanical watch housing, and a mechanical watch face retained at least partially within the mechanical watch housing; a first watch band portion; and a second watch band portion. The watch can further include a circuit board associated with a controller, the circuit board and controller being at least partially retained by a clasp. The circuit board and the controller can be electronically and operatively independent from the mechanical watch.
