    摘要： The invention discloses a pointer type Bluetooth intelligently time-corrected clock movement, comprising a movement body (1), wherein the bottom of the movement body (1) is provided with a cell box (2); the surface of the cell box (2) is provided with a disassembling hole (3); an hourly chiming module (4) is provided at one side of the cell box (2); a central microprocessor (5) is provided at one side of the hourly chiming module (4); a Bluetooth communication module (6) is provided at one side of the central microprocessor (5); a power management circuit (7) is provided at the other side of the cell box (2), and a display screen (8) is provided at one end of the power management circuit (7). According to the invention, through an integrated technological application of "optics, electron, mechanical transmission and wireless communication", the control over a mechanical gear assembly is accomplished; through wirelessly receiving time information on an APP software and combining an operating principle of the central microprocessor (5) controlling over a core plate and an optic-coupling device (11), a novel automatically time-corrected clock product is accomplished. The pointer type Bluetooth intelligently time-corrected clock movement is relatively practical, relatively high in precision, free of influences from factors of geography, signals and the like, and is suitable for broad promotion and use.

    摘要： A method and apparatus for determining a drift between a local clock of a movable device and a reference clock that is used by one or more reference devices. The local clock may be calibrated at a calibration location and then the movable device may be moved to an operating location that is different from the calibration location. The drift is determined by observing one or more signals transmitted by the respective one or more reference devices, when the device is at the calibration location and when it is at the operating location. These observations are used together with a model of the signals to determine the drift.
