Automated Student Attendance Tracking Script

Develop a robust Bash script that parses multiple CSV attendance logs from different campus locations, consolidates data, and generates daily/weekly attendance reports. The script must handle variable file formats, validate timestamp entries, and output normalized attendance percentages. Include error handling for corrupted files, logging mechanisms, and the ability to flag suspicious attendance patterns. Requirements: Support multiple input formats, handle timezone differences, and integrate with a potential learning management system API.
