Discover how reliable NTP is for clock synchronization and what factors can affect its accuracy.

36 views

NTP (Network Time Protocol) is highly reliable for synchronizing clocks across computer systems to within milliseconds. It uses a hierarchy of time sources, often rooted in atomic clocks and GPS, to maintain accuracy. However, network delays and jitter can impact its precision momentarily. Keeping systems updated and using multiple time sources can further enhance reliability.

FAQs & Answers

  1. What is the purpose of NTP? NTP synchronizes the clocks of computer systems, ensuring accurate timekeeping across networks.
  2. What causes NTP to be inaccurate? Factors like network delays and jitter can temporarily affect NTP's precision.
  3. How can I improve NTP reliability? Using multiple time sources and keeping systems updated can enhance NTP reliability.
  4. What are the time sources used by NTP? NTP typically uses atomic clocks and GPS as its primary time sources.
