Encyclopedia > Real Time Clock

A real-time clock (RTC) is a computer clock (most often in the form of an integrated circuit chip) that keeps track of the current time even when the computer is turned off. It is used in many kinds of computers, and is present in all modern personal computers. RTCs are also present in many embedded systems, though this should not be confused with real-time computing. The tower of a personal computer (specifically a Power Mac G5). ... A clock (from the Latin cloca, bell) is an instrument for measuring time. ... An integrated circuit (IC) is a thin chip consisting of at least two interconnected semiconductor devices, mainly transistors, as well as passive components like resistors. ... An embedded system is a special-purpose computer system, which is completely encapsulated by the device it controls. ... Real-time computing is the subject of hardware and software systems which are subject to constraints in time. ...


Real-time clocks run on a special battery that is not connected to the normal power supply. In contrast, clocks that are not real-time do not function when the computer is off. Do not confuse a computer's real-time clock with its CPU clock. The CPU clock regulates the execution of instructions. The clock rate is the fundamental rate in cycles per second, measured in hertz, at which a computer performs its most basic operations such as adding two numbers or transferring a value from one processor register to another. ...

Telling Historic Preservation Time (3022 words)
Without discussion or debate, scientists, historians, and poets would agree that time is the continuum of change, that a clock's rotating hands are synonymous with movement forward in time, and that, since the clock only represents time, if a clock stops, real time does not stop.
If real time declares that loss is inevitable, the most obvious solution would be to acknowledge it, leave a blank spot in the work, and simply interpret the loss.
Real stories about real lives shouldn't be skewed or erased or manipulated to "make a buck" or "simply look pretty." Historic preservation treatments should always be as honest and respectful as possible toward people from the past, the built environment, and time.
