Embodiments of 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 watch can include a butterfly clasp having a digital display and a circuit board associated with a controller.

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.

An information processing method and an electronic device are provided. The method includes displaying a first identifier indicating time information on a display unit of an electronic device; acquiring first operating state information indicating a first operating state of a first functional unit of the electronic device; determining a first display state of the first identifier based on the first operating state information; and controlling the first identifier to be displayed at the first display state to indicate that the first functional unit is in the first operating state. With the method and electronic device of the disclosure, the display area of the display unit can be efficiently used without occupying a specified display area on the display unit to indicate operating state information of the electronic device.

The conventional demand target display device based on time information differing from the information used by electric power companies and electric power consumers causes a divergence regarding their demand values. Therefore, a demand target display device with a dual-purpose scale, which acquires AC signals based on the AC waveform of AC power from a power supply line, generates time information based on the acquired AC signals, transmits the generated time information via radio waves within a housing, receives the transmitted time information via radio waves within the housing, indicates the time on the dual-purpose scale based on the received information, acquires electrical energy consumption within a segment for a given target demand value including the current time, and indicates the relationship between the acquired electrical energy consumption within a segment recorded and a target demand value set for such segment, is proposed.

A wearable electronic device having an analog display and a digital display. The device may include a receiver for receiving, from a remote source, current time information data representative of a current time; a controller, operatively coupled to the receiver, wherein the controller processes the current time information data received from the remote source and provides for the current time information data to be displayed by the at least one digital indicator on the digital display as the current time; and a an analog time indicator rotating arrangement for causing the rotation of the at least one analog time indicator until the at least one analog time indicator is aligned with the at least one digital indicator; whereby the alignment of the at least one analog time indicator with the at least one digital indicator indicates that the at least one analog time indicator is synchronized with the correct time information.
