NTP is the abbreviation of Network Time Protocol and PTP is the abbreviation of Precision Time Protocol. NTP provides millisecond accuracy while PTP provides sub-microsecond accuracy.

Precision Time Protocol (PTP) is a protocol to synchronize clocks in a computer network, similar to Network Time Protocol (NTP). NTP is accurate, under ten milliseconds. PTP, however, is …

For all other Windows operating environments, PTPSync is a Windows service that can be used to synchronize the operating system clock to within a few microseconds of precision on most local networks (see Windows Time Precision) when used with a clock that supports PTP.

Jun 20, 2022 · Precision Time Protocol (PTP) is a protocol that promotes the synchronization of clocks throughout a computer network. This protocol is used to synchronize clocks of different types of devices. PTP was led by John Edison in 1588 for the standardization and was published in the year 2002.

Mar 18, 2025 · Precision Time Protocol (PTP) is a time synchronization protocol that synchronizes clocks throughout a computer network as defined in the IEEE 1588 standard, Precision Clock Synchronization Protocol for Networked Measurement and Control Systems. PTP clock synchronization in packet-based network infrastructure includes distributed internal device clocks that help organize data packets ...

The PTP is a time-transfer protocol defined in the IEEE 1588-2008 standard that allows precise synchronization of networks, for example, Ethernet. Accuracy within the nanosecond range can be achieved with this protocol when using hardware generated timestamps.
