119 views

Time on a computer is stored using the system clock in the form of a timestamp. This covers the number of seconds since the Epoch (January 1, 1970). Operating systems regularly sync with Network Time Protocol (NTP) servers to maintain accuracy.

FAQs & Answers

  1. What is the Epoch in computer time storage? The Epoch is the reference point of time in computing, set to January 1, 1970, from which timestamps are calculated.
  2. What is the role of the Network Time Protocol? The Network Time Protocol (NTP) is used to synchronize system clocks with accurate time servers, ensuring time consistency across devices.
  3. How does a system clock keep time? A system clock maintains time by counting clock ticks since the last sync, adjusting regularly through protocols like NTP for accuracy.
