NetTime - Network Time Synchronization Tool. NetTime is a Simple Network Time Protocol (SNTP) client for Windows 95/98/Me/NT/2000/XP/Vista/7/8/10/11 and Server 2003/2008/2012/2016/2019/2022. (32 bit and 64 bit operating systems are both supported and future versions are expected to work without needing to update NetTime)
The Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. In operation since before 1985, NTP is one of the oldest Internet protocols in current use.
27 cze 2022 · A time difference of less than 128ms between server and client is required to maintain NTP synchronization. The typical accuracy on the Internet ranges from about 5ms to 100ms, possibly varying with network delays.
31 maj 2023 · The Windows Time service follows the Network Time Protocol (NTP) specification, which requires the use of UDP port 123 for all time synchronization. Whenever the computer synchronizes its clock or provides time to another computer, it happens over UDP port 123.
Serwery czasu znajdują się w Głównym Urzędzie Miar, w Laboratorium Czasu i Częstotliwości. Są one synchronizowane z państwowego wzorca jednostek miar czasu i częstotliwości. Do transferu czasu używany jest protokół NTP (szczegółowe informacje na temat protokołu znajdują się na witrynie www.ntp.org). Sposób synchronizacji ...
Network Time Protocol (NTP) is a networking protocol devised to synchronize the clocks of computers over a data network. Originally developed by David L. Mills in 1985, NTP operates over the User Datagram Protocol (UDP) and aims for high accuracy and fault-tolerant timekeeping.
The NTP Project conducts Research and Development in NTP, a protocol designed to synchronize the clocks of computers over a network to a common timebase. NTP is what ensures the reliability of billions of devices around the world, under the sea, and even in space.
