Multiprocessor systems such as NUMA or SMP have multiple instances of clock sources. The way clocks interact among themselves and the way they react to system events, such as CPU frequency scaling or entering energy ... A real-time clock (RTC) is an electronic device (most often in the form of an integrated circuit) that measures the passage of time. Although the term often refers to the devices in personal computers, servers and embedded systems, RTCs are present in almost any electronic device which needs to keep … See more The term real-time clock is used to avoid confusion with ordinary hardware clocks which are only signals that govern digital electronics, and do not count time in human units. RTC should not be confused with See more Most RTCs use a crystal oscillator, but some have the option of using the power line frequency. The crystal frequency is usually 32.768 kHz, the same frequency used in See more Many integrated circuit manufacturers make RTCs, including Epson, Intersil, IDT, Maxim, NXP Semiconductors, Texas Instruments, STMicroelectronics and Ricoh. A common RTC … See more • Media related to Real-time clocks at Wikimedia Commons See more Although keeping time can be done without an RTC, using one has benefits: • Low power consumption (important when running from alternate power) • Frees the main system for time-critical tasks • Sometimes more accurate than other methods See more RTCs often have an alternate source of power, so they can continue to keep time while the primary source of power is off or unavailable. This alternate source of power is normally a lithium battery in older systems, but some newer systems use a supercapacitor, … See more • Crystal oscillator frequencies • High Precision Event Timer • IRQ 8 See more

WebRTCs often provide alarms and other interrupts. All i386 PCs, and ACPI-based systems, have an RTC that is compatible with the Motorola MC146818 chip on the original PC/AT. Today such an RTC is usually integrated into the mainboard's chipset (south bridge), and uses a replaceable coin-sized backup battery.
