    This is great stuff, both the exposition and the work itself. It’s stories like these that keep me coming back to Lobsters.

    But… I couldn’t help but wonder, why even parse in the first place? If you have control over whatever’s emitting those timestamps and don’t need to validate, why not just use a binary format directly? It would be nice to see that option at least mentioned in the writeup.
