CydandClaude Opus 5 2bd824e16e The clock counts from launch, not from boot 
Chasing the tick turned up why its period looked quantised: every interval
the trace reported was a multiple of 1/32s, which is the spacing between
representable float32 values near 474196 - this machine's uptime in
seconds. GetRTC returned QueryPerformanceCounter scaled to milliseconds
since BOOT, so (Scalar) Now() was a number near half a million and had
lost resolution accordingly.

That is not only a measurement problem. Scalar is a 32-bit float, so any
absolute time held in one degrades as the number grows: 3.9ms apart after
nine hours of uptime, 15.6ms after a day and a half, 31.25ms after three
days - past which the clock cannot resolve a single 20ms physics step.

Two places subtract absolute times in float and inherit it. L4CTRL polls
the joystick when (Scalar)Now() - lastJoystickUpdate exceeds 50ms, and
lastJoystickUpdate is a Scalar, so that test becomes 62.5ms after three
days of uptime and 125ms after twelve: a player's controls get less
responsive the longer their machine has been switched on, with nothing on
screen to explain it. The smoke emitter in L4VIDRND compares myLastSmoke
plus an interval against now, and once the interval falls under the
spacing the addition rounds to no change at all.

Separately, GetRTC returns a long, and milliseconds since boot overflow
one after 24.8 days.

Counting from launch fixes the whole class at the source. Every Time
arithmetic path is untouched, because those subtract ticks as integers and
were always exact - which is also why the simulation itself was never
affected, and why the render fraction measured clean. The origin is taken
in Startup rather than on first use, so it is fixed before anything reads
the clock and no two threads can race to set it.

Peer machines already disagreed about this origin, having booted at
different moments, so the network is no worse off; reconciling that is
what RP412NETCLOCK does.

The fix is self-checking: the trace's interval readings should stop being
multiples of 0.03125.
