## Resource

Episode 75 of Networking Tech with Fexingo digs into Network Time Protocol (NTP) and Precision Time Protocol (PTP) — the invisible infrastructure that keeps financial exchanges, 5G networks, and power grids in sync. Lucas and Luna break down the June 2026 SEC mandate requiring all US stock exchanges to achieve microsecond-level timestamp accuracy, using real examples like the 2012 Knight Capital trading glitch and the 2021 Facebook DNS outage. They explain why NTP alone isn't enough for modern high-frequency trading, how PTP achieves sub-microsecond precision via hardware timestamping, and the role of atomic clocks in data centers. The episode also covers practical challenges like asymmetric network paths and the upcoming leap second removal in 2035. A concrete look at why time is the most critical network measurement you never think about. #NetworkTimeProtocol #PrecisionTimeProtocol #HighFrequencyTrading #SECRegulation #NTP #PTP #TimeSynchronization #FinancialNetworking #AtomicClocks #LeapSecond #KnightCapital #TradingInfrastructure #NetworkEngineering #Technology #FexingoBusiness #BusinessPodcast #Latency #TimestampAccuracy Keep every episode free: buymeacoffee.com/fexingo
