Rtc clock source
WebReal-Time Clock in Linux. Two clocks are important in Linux: a ‘ hardware clock ’, also known as RTC, CMOS or BIOS clock. This is the battery-backed clock that keeps time even when the system is shut down. The second clock is called the ‘ system clock/tick ’ or ' kernel clock ' and is maintained by the operating system.
