Has anyone built a stream processor that uses TrueTime/GPS clocks/PTP? 🤔

I built a small interactive visualizer for Hybrid Logical Clocks (HLC).
I used Claude Code to put this together quickly and make the behavior visible step by step.

I wish DynamoDB had some bounded staleness knob or SLA for eventually consistent reads, like Spanner does. Just like TrueTime enables it for Spanner, AWS does have the primitive with ClockBound.

The Google Spanner paper is a 10/10 read.
The most interesting bit? TrueTime, an API that gives time results with error bounds, and one that guarantees <= 7 ms of clock skew. Impressive!
The downside? Not OSS. Even if it were, would require reproducing the timing hardware.

You could do a Bayesian hierarchical linear model. Something like: TrueTime ~ norm(BadEst + Err, SD); BadEst ~ norm(0, SD). The accuracy would improve if you have covariate data you could include too. Then BadEst could also depend on covariates.
