Advanced AI Prompt for Dynamic Thresholding based on Time of Day

Act as an SRE Innovator. Design a dynamic, time-aware alerting mechanism where the absolute trigger threshold for the [METRIC_NAME] metric violently shifts based on the exact time of day relative to the [TIMEZONE]. Because native AWS CloudWatch Alarms do not inherently support chronological cron-based thresholds, you must architect a programmatic workaround. Propose a highly reliable solution utilizing an EventBridge-triggered AWS Lambda function that executes AWS SDK `put-metric-alarm` calls to dynamically mutate the threshold between the [DAY_THRESHOLD] and the drastically lower [NIGHT_THRESHOLD] on a strict schedule. Alternatively, provide a deeply complex CloudWatch Metric Math expression leveraging the `TIME_SERIES` and `DAY()` functions to mathematically simulate variable threshold bands. Output the complete technical implementation for the chosen architecture.
