Two wall clocks, one mocked skew, one LWW burial Two wall clocks, one mocked skew MOCK is a shifted clock in a demo, never a measurement host A wall (truth time) NTP step -500ms A writes at truth t+100, wall stamp t-400 truth time host B wall (MOCK +250ms) B writes at truth t, wall stamp t+250 truth time same truth t truth t+100 LWW keeps B: 250 is newer than -400 the earlier write buries the later one sample: A asks B, RTT 40ms, raw diff 250ms uncertainty +-20ms travels with the sample spans on monotonic per host, stamps on wall, order never on wall two containers on one host share a clock: use two hosts or label the MOCK monotonic readings never cross hosts: different zeroes
