An electronic timepiece includes: a bezel having location markers for indicating positions of the world; a second hand moving relative to the bezel; a memory storing time difference information in which each location marker is associated with information relating to a time zone to which a position indicated by each location marker belongs; and a controller performing operation control for moving the second hand relative to the bezel, and the bezel has a set exception indication position representing non-correspondence to any time zone associated with each location marker by being in a predetermined positional relationship with the second hand, and the controller causes the second hand and the exception indication position to be in the predetermined positional relationship when there is no location marker associated with a set time zone, during display relating to the set time zone for a date and time to be displayed.

A time display apparatus for indicating time in a plurality of time zones simultaneously, the apparatus includes a case having a compartment enclosed by a cover, the case having a dial member indicating a 12-hour time clock and a 24-hour time clock, a first wheel completing one revolution in 12 hours and coupled to an hour hand, a second wheel completing one revolution in 1 hour and coupled to a multi-zone minute hand having at least two different vertices, and a third wheel completing one revolution in 24 hours and coupled to a multi-zone hour indicator hand having at least two different indicators, wherein each vertex of the multi-zone minute hand indicates a different minute marking on the 12 hour time clock and each indicator of the multi-zone hour indicator hand indicates a different hour marking on the 24 hour time clock corresponding to different time zones.

According to an aspect of the present invention, a device capable of wireless communication includes a counter for counting current time, and a processor for setting a communication mode of the device to one of a notification mode in which the device sends a first notification signal for informing of its existence and a detection mode in which the device detects a second notification signal sent from other device. In the case that the processor changes the communication mode of the device from the notification mode to the detection mode and the second notification signal received in the detection mode includes first time information, the processor corrects time of the counter based on the first time information.

A control device for power supply time of timers comprises an alternative current (AC) power source input module, a direct current (DC) power source supply module, an AC power source output module electrically connected to a load end, a relay, a central control module, a relay driver circuit, a day/night detecting module, a power supply time backward display light set, a power supply time forward display light set, a power supply time backward selection control button and a power supply time forward selection control button. Herein, by pressing the power supply time backward selection control button or the power supply time forward selection control button, one of the power supply time backward display lights or the power supply time forward display lights can be turned on such that the central control module can, based on the sunset time of the previous day as well as the configured power supply backward setting time or power supply forward setting time, postpone or advance the power supply time for the load end in the next day, and then record the sunset time of the next day so as to control the power supply time for the load end in the further next day.

A world watch capable of automatically adjusting displayed information otherwise indicating time of day around the world upon occurrence of a daylight savings time event.

A watch bezel provides a GMT function and a count-up time-tracking function. The watch bezel includes a first set of indicia to indicate 24 hours associated with the GMT function of the watch and a second set of indicia to indicate 60 minutes in an hour. When mounted or attached to the watch casing or body, the bezel is rotatable in the clockwise direction and in the counter-clockwise direction. The watch bezel enables a user to read or set the time associated with a secondary time zone without adjusting any hands on the watch. The second set of indicia comprises a plurality of incremental minute markers and allows a user to track elapsed time. The capability of tracking elapsed time allows the watch to be used in activities that require tracking of elapsed time such as diving or other sporting events.
