> If I want my Starliner thruster to fire at a precise offset, hopefully I'm using something like CLOCK_MONOTONIC, CLOCK_TAI, or Barycentric Dynamic Time.
CLOCK_MONOTONIC sounds like a bad idea for precise thrusting, since it "is affected by the incremental adjustments performed by adjtime(3) and NTP" (per the man page), so 1 second on that clock may not be 1 second in real time. CLOCK_MONOTONIC_RAW sounds a bit safer.
(Both of those have an unspecified starting point though, so they probably wouldn't have saved Boeing from their Starliner issue where it missed the desired orbit because a clock was off by 11 hours.)
