WebJun 20, 2024 · 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. This is required in achieving the … WebSep 21, 2024 · PTP over raw ethernet isn't supported. Timestamping is supported for PTPv2 operating in 2 step mode. 2 step refers to the mode in which the actual timestamps in the PTP packets aren't generated on the fly in the hardware, but are instead retrieved from the hardware and conveyed as separate messages (for example, using a follow-up …
