How Software Keeps Accurate Time Using Real-Time Clocks

Discover how software maintains time accuracy using clocks and protocols like NTP.

50 views

Software keeps time using the system clock, which is typically maintained by the computer’s hardware-based Real-Time Clock (RTC) and synchronized via Network Time Protocol (NTP) servers. The time is often represented in UNIX time (seconds since January 1, 1970) to ensure accuracy and consistency.

FAQs & Answers

  1. What is a Real-Time Clock (RTC)? A Real-Time Clock (RTC) is a hardware device that keeps track of time even when the computer is turned off.
  2. How does the Network Time Protocol (NTP) work? NTP synchronizes clocks of computers over a network to ensure they reflect the correct time.
  3. What is UNIX time? UNIX time is a system for tracking time that counts the number of seconds since January 1, 1970.
  4. Why is time synchronization important in computing? Time synchronization is crucial for scheduling tasks, logging events, and coordinating distributed systems.
