ABSTRACT:
A time setting device for setting time in a computer based operating system. The time setting device utilizes a random access memory (RAM) in which an operating system is loaded and the operation thereof is performed, a real time clock (RTC) for tracking real time and the date, and storing corresponding data in a corresponding register, a power management system controller for sensing whether an activity signal according to data input or reception/transmission of data is generated, and generating a clock driving signal according to a sensed result, a clock generator for outputting a clock signal according to the clock driving signal generated by the power management system controller, a central processing unit operated according to the clock signal output by the clock generator, and a device driver for resetting the time and the date of the operating system according to the time and date measured by the real time clock after determining that the central processing unit is in a stop clock state when the time and the date measured in the operating system is delayed when compared to the time and the date measured by the real time clock after reading the real time clock for the time and the date, and reads the time and the date measured by the real time clock and the operating system at predetermined time periods.
