Network Time Protocol is used to synchronize the clocks of computers on a network. How accurately it synchronizes the clocks of client computers depends on a number of factors. However, the following timings can be used as a guide: Public Internet NTP Servers: <10ms. Public Internet Servers over asymmetric connection (ADSL): <100ms. NTP Servers on […]

How Local Time And Time Zones Are Handled By NTP
Local time varies by a time zone offset which is applied according to the longitude of the location. However, NTP does not use local time. NTP utilizes Universal Coordinated Time (UTC), it does not recognize time zones. UTC is a time standard which is not adjusted for time zones or daylight saving time (DST). Universal […]
How NTP Handles Daylight Saving Time Adjustments
Many countries make daylight saving time adjustments during the summer months. Typically, local time is advanced by one hour in the spring and set back one hour in the autumn. However, NTP utilizes Universal Coordinated Time (UTC) rather than local time. UTC is not adjusted for local time zones or daylight saving (DST). Universal Coordinated […]
SNTP: All You Need To Know About Simple Network Time Protocol
Simple Network Time Protocol (SNTP) is an Internet Protocol (IP) used to synchronize the clocks of networks of computers. SNTP is a subset of the Network Time Protocol (NTP). The latest version is SNTP v4. It can synchronize seamlessly to full-blown NTP servers. Originally developed for small computers and micro-controllers. Requires less memory and processing […]
Ten Reasons To Buy A NTP Server
The Internet has many NTP servers that can be used to synchronize the time of networks and computers. Most provide a service completely free of charge. So why do organizations need to seriously consider buying a dedicated NTP appliance? Dedicated hardware time references installed locally, within an organization, provide a number of advantages over Internet […]
Network Time Protocol (NTP) Best Practices
By implementing a few best practice principles, organisations can attain robust and reliable timing for their network infrastructure: Install 3 or more redundant Stratum 1 NTP servers. Configure lower stratum clients with at least 3 higher stratum servers. Peer lower stratum devices to share time. Secure NTP communications with authentication. Employ Stratum 1 servers that […]
