Systems and methods for displaying an adjusted time to a user are provided. A time display device that normally displays the correct time is used to display a modified time. This modified time is unknown to the user so that the user cannot know what the time offset is and is forced to assume that the current time is displayed. The modified time may be an advanced time or a time that is set backwards, depending on when the user wants to arrive at an event.

Provided is a watch-type terminal including: a main body that includes an antenna module which transmits and receives a wireless signal in a predetermined frequency band; a band that extends from the main body and that is formed in such a manner that the main body is removably worn on a wrist; a ground portion that includes first and second metal members that extend to have different lengths; a sensing unit that detects whether or not the main body is worn on the wrist; and a controller that grounds the antenna module to at least one of the first and second metal members, based on whether or not the main body is worn on the wrist.

The fixed-time reception control section carries out the reception process at first time to acquire first reception time data and compares the acquired first reception time data with the internal time. When a difference in time between the first reception time data and the internal time is greater than or equal to a first threshold, the fixed-time reception control section carries out the reception process at second time different from the first time to acquire second reception time data. The time correction section compares the acquired second reception time data with the internal time and corrects the internal time based on the second reception time data when a difference in time between the second reception time data and the internal time is smaller than a second threshold.

A smart wristwatch structure includes a glass, a dial, a watch case, a bottom case, a movement, an antenna, a functional module, and a dedicated battery. The dial, the watch case, and the bottom case construct an accommodating space from top to bottom. The antenna is adhered a lower surface of the glass. The functional module is disposed in the accommodating space for wirelessly communicating with a mobile terminal. The dedicated battery provides power for the functional module or the movement. In the smart wristwatch structure, signals are not shielded, and the thickness of the watch case is not increased significantly.

An electronic timepiece including: a clocking unit which counts current date and time; a daylight saving time application unit which applies daylight saving time information corresponding to positional information to the date and time counted by the clocking unit; a radio wave reception unit which receives radio waves including daylight saving time implementation information of a predetermined area; a daylight saving time information acquisition unit which acquires the daylight saving time implementation information from the received radio waves; a storage unit in which a daylight saving time implementation rule of each area in the world is stored in advance; and an information selection unit which selects, as the daylight saving time information, one of the daylight saving time implementation information and the daylight saving time implementation rule corresponding to a current position on the basis of the current position and the daylight saving time implementation information.

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.

Generally discussed herein are systems, apparatuses, and methods for providing an accurate and stable time base. A device can include a voter to receive a plurality of time source values, determine a central time value, and determine which of the plurality of time source values are valid, a deviance checker to determine a deviance set, a discrete time selector to provide a selector identification identifying which of the time source values is selected, and a network interface to provide a time value based on the selected time source value.
