摘要： A time-error-compensating apparatus and method corrects errors in a real-time clock caused by temperature fluctuations or other external influences. The apparatus includes a frequency counting unit which counts a high-frequency clock signal and a low-frequency clock signal, and a time compensating unit which computes a clock count compensation value based on a comparison of the count values of of the low-frequency and high-frequency clock signals. Correcting time using a high-frequency clock is highly desirable because a clock of this type has proven to be accurate in high external stress conditions. Use of this clock also allows the real-time clock to be implemented as a low-frequency, inexpensive low-frequency clock. The method and apparatus are well suited to correcting time information in the terminals of a mobile communications system, or in any other system or device where time tracking is sought.

摘要： A terminal device such as a mobile terminal is provided with two real-time clocks which are powered by different power sources: a first real-time clock which is built in a control section (built-in microcomputer 1, for example) of the terminal device; and a second real-time clock which is provided outside the control section. At power-on of the mobile terminal or on recovery from failure such as a power cut, clock/calendar information is read out from the second real-time clock and is set to the first real-time clock, and thereafter, the control section obtains the clock/calendar information from the first real-time clock. The second real-time clock is connected to the control section directly by a signal line or via a functional device, or the second real-time clock is built in a functional device which is connected to the control section. By such composition and operation, the clock/calendar information can be maintained reliably and correctly even if failure occurred to the control section. The readout of the clock/calendar information is carried out usually from the first real-time clock (built-in RTC), therefore, high readout speed can be realized.

摘要： A wireless synchronous time system comprising a primary master event device and secondary slave devices. The primary event device receives a global positioning systems “GPS” time signal, processes the GPS time signal, receives a programmed instruction, and broadcasts or transmits the processed time signal and the programmed instruction to the secondary slave devices. The secondary slave devices receive the processed time signal and the programmed instruction, select an identified programmed instruction, display the time, and execute an event associated with the programmed instruction. The primary event device and the secondary devices further include a power interrupt module for retaining the time and the programmed instruction in case of a power loss.

摘要： A computer date and time clock including an incrementing binary 32 bit register, used to main elapsed date and time in seconds, and an external 1 Hz clock signal, provided by an oscillator, that increments the register. The oscillator and register are both powered by a battery, to make them independent of computer system power. On computer systems having a 32 bit bus, the register can be read or written with a single I/O cycle on the system bus. Operating system software typically performs time calculations using elapsed seconds since a fixed date and time, thus the register count can represent a number of seconds since the fixed date and time. The 1 Hz clock signal is derived from a higher frequency oscillator using a divider circuit, and a reset circuit within the date and time clock clears the divider circuit each time data is stored in the register.
