CRITICAL ISSUES FIXED
1. TIMEZONE MISMATCH (HIGH RISK) - FIXED
Problem: Dates compared in UTC while cron runs in local timezone → off-by-one day errors
Solution: Implemented robust timezone handling using Luxon DateTime library
2. DATE PARSING FRAGILITY (HIGH RISK) - FIXED
Problem: Basic new Date() parsing could fail silently with invalid dates
Solution: Created comprehensive parseDate() function handling multiple formats with validation
3. DATE CALCULATION ERRORS (MEDIUM-HIGH RISK) - FIXED
Problem: Month arithmetic had edge cases (Jan 31 + 1 month = March 3 instead of Feb 29)
Solution: Implemented addTimePeriod() using Luxon's robust date arithmetic
4. MISSING VALIDATION & ERROR HANDLING - FIXED
Added comprehensive validation for all maintenance event data
Enhanced error handling to prevent system crashes
Added overdue detection as safety net (1-3 days past due notifications)
🛡️ SAFETY MECHANISMS ADDED
Overdue Detection: Catches missed maintenance (server downtime scenarios)
Duplicate Prevention: Tracking system prevents multiple notifications for same event
Data Validation: Invalid events are skipped with logging, don't crash system
Comprehensive Logging: Detailed debugging and summary reports
📊 TEST RESULTS
