How is this possible in its simplest form?Network Time Protocol (NTP) is a protocol which enables computers to synchronize their clocks over network. Time is distributed from primary time servers to clients, which can be servers for other clients, and so on. Clients can use multiple servers simultaneously. ¶. NTPv5 is similar to NTPv4 [ RFC5905].The NTP on-wire protocol reads the SCI on two occasions: when a packet arrives and when a packet departs. In either case the SCI is subject to operating system and hardware latencies. The operating system latency typically involves a context switch in order to map the kernel address space, as well as hardware latencies to either lock the system ...For all of the excitement pulsing through the so-called web3 space in the past year, most of the heartiest sums of investor dollars have seemed to find their way toward products to...Learn about the architecture and operation of NTP, a protocol for synchronizing computer network time across the Internet.
