How Does a Computer Keep Accurate Time?

Discover how your computer maintains time with a Real-Time Clock and internet synchronization.

98 views

Your computer keeps time using a Real-Time Clock (RTC) that functions even when the PC is off. Powered by a small battery, the RTC maintains time and date settings. When your computer is on, it often synchronizes with internet time servers to ensure accuracy. To check or update the time settings, go to your system's clock settings.

FAQs & Answers

  1. What is a Real-Time Clock (RTC)? A Real-Time Clock (RTC) is a battery-operated clock that keeps track of time even when the computer is off.
  2. How often does my computer synchronize its time? Typically, your computer synchronizes its time with internet time servers at regular intervals to maintain accuracy.
  3. Can I manually change the time on my computer? Yes, you can check or update your time settings through your system's clock settings.
  4. Why is my computer's time sometimes incorrect? Your computer's time might be incorrect due to issues with the RTC battery or improper synchronization with time servers.
