An air conditioning (HVAC) system for a residential dwelling or other building with enclosed spaces includes multiple thermostats hard wire interconnected or communicating via radio frequency transceivers. The thermostats each include control circuits for adjusting the setpoint temperature at any one thermostat and displaying the set temperature at all thermostats, setting the time at any one thermostat and displaying the time at all thermostats, controlling the thermostat temperature setting from a selected one of the thermostats and providing a setpoint for control of the air conditioning system based on an average temperature sensed by all of the thermostats. A method for correctly setting a thermostat time display to one of Daylight Saving Time or Standard Time and displaying an icon identifying one or the other is disclosed.

A display device for deriving geographic location from a GPS signal or the Internet and cross referencing the location with a database to determine the adjustment required to display correct time regardless of time zone and daylight savings time. Thus, a device may be sold and / or transported anywhere in the country and / or world and display the current time.

A novel and useful system and method for extracting timing, time and additional information from a broadcast received in a radio controlled clock (RCC) receiver. The RCC receiver extracts timing information represented by a known synchronization sequence that is used for acquisition and tracking purposes. The RCC receiver extracts time information as a merged 26-bit time information word linearly coded into 31 bits comprising the number of minutes (or hours) since the turn of the current century. A minute counter representing the 26 bits is converted into the date, hour, and minute. The RCC extracts additional information including the schedule for the next daylight saving time transition and for an imminent leap second. The communications protocol optionally employs error correcting codes to provide protection for data fields in the frame, which the RCC may use to enhance reception reliability in the presence of noise and interference.

A time keeping system having a first time module operable to keep a first time, a second time module operable to keep a second time, and a control module operatively coupled to the first time module and to the second time module. The control module adjusts the first time in response to information stored in the control module and adjusts the second time to reduce a time difference between the first time and the second time.

The present invention provides apparatuses and methods for updating a target device from a clock device through a network. The clock device obtains a time value from a clock source and sends the time value to a target device. A node within the network determines a time delay, adjusts the time value in accordance with the time delay, and sends the adjusted time value to the target device. The node may determine a time delay from an internal timer or from a measurement message when adjusting the time value. The clock device may send a subsequent time update message to the target device if the target device does not acknowledge reception of a time update. The clock device may also send a time update message to a target device when a status change of daylight savings time occurs and obtain a subsequent time value from a clock source.

A method of updating DST information in a wireless terminal is provided, whereby the wireless terminal correctly and conveniently provides world time in consideration of the DST information. The method includes the steps of: transmitting, by a second server receiving DST information in real-time, the received DST information to the wireless terminal; and if the DST information is received, updating, by the wireless terminal, DST information of the wireless terminal based on the received DST information. The method also includes the steps of: requesting, by the wireless terminal, a second server for an update of DST information; if the DST information update request is received from the wireless terminal, transmitting, by the second server, DST information, which is received in real-time, to the wireless terminal; and if the DST information is received from the second server, updating, by the wireless terminal, DST information of the wireless terminal based on the DST information received from the second server.

The invention relates to an analog display watch that comprises two separate time displays (40, 44) for a first and second time zone, and a time zone indicator (50) comprising a place ring (53) associated with two counters (51, 52) that are angularly offset by 1 / 24 of a turn, one of which is used in combination with Standard Time and the other with Daylight Savings Time (DST). A primary manual time set device (31) enables the first and second time displays (40, 44) to be set separately. A second manual time set device allows the entire device to turn the second time display (44) and the time zone indicator (50) together step by step without modifying the status of the first time display (40). A manual corrector (34, 63) enables the place ring (53) to turn step by step without modifying the status of the first and second time displays (40 and 44). Place symbols (54) are distributed on the circumference of the place ring (53) with a step of a 1 / 96 turn, such that the place symbols (54) include symbols (54a, 54b) that represent time zones that differ by a number of hours that is not a whole number relative to Coordinated Universal Time (UTC). With these characteristics, simple manipulations will enable the time at any place in the world to be displayed, and changes to time zones to be made easily, taking into account Daylight Savings Time and a change of hemisphere, if applicable.

A before / after specific weekday determination device that determines if an evaluation date is before or after a specific date that is identified as an n-th (where n is an integer of 1 or more) specific weekday from the beginning or the end of a specific month. The before / after specific weekday determination device is utilized in a daylight saving time determination device, and in a timepiece.

The invention relates to a method for updating a time marking according to new location, wherein a country related information is detected, a need for time update is determined, and if needed, time rules corresponding to said country related information is retrieved and the time is updated according to said rules. The invention relates also to a system, to a device, to a update converter and to computer program product.
