Thread: Computer’s Internal Clocks

I started learning about Hardware peripherals that needed for synchronization. But I want to know about computer’s Internal Clocks and doesn’t getting help from anyone. So please provide me some suggestions about this. Any help will be appreciated.

Every PC has included electronic clock and calendar. In earlier days there were only clocks in system tray, time now for few programs, you get good analog clock with air over wristwatches. Value of internal clock is got through OS, it is in hour-minute format milliseconds. Though, as internal clocks of PCs are right about measuring time elapsed, time specified on specific PC is most likely not right in absolute terms. But wrist watch and clock on wall as PC clocks are off by some seconds or minutes. Also internal PC clocks are not coordinated among them.
