HN discussion"1,000,000 journal entries per second on consumer-grade hardware." Of cause you could just add a few cents more per device hardware to not get a rock bottom clock. Or add a temperature Sensor and start modeling a drift compensation: https://blog.dan.drown.org/rtc-comparison/ Or why reinvent a homebrew version of what looks like PTP IEEE 1588: https://blog.meinbergglobal.com/2013/09/14/ieee-1588-accurat...
