console.log('=== convertTimezone Phase 4 Analysis ===\n');
console.log('Current State:');
console.log('- Complexity: 11 (limit: 10)');
console.log('- Lines: 57 (limit: 50)');
console.log('- Already extracted: validation, parsing, formatting\n');
console.log('Remaining Complexity Sources:');
console.log('1. String validation conditionals (lines 209-214)');
console.log('2. Cache check conditional (lines 223-226)');
console.log('3. Try-catch block');
console.log('4. Custom format conditional (lines 246-250)');
console.log('5. Error type checking conditionals (lines 271-274)\n');
console.log('Potential Extractions:');
console.log('\n1. Cache Management Helper:');
console.log(' - getCachedResult(cacheKey)');
console.log(' - cacheResult(cacheKey, result)');
console.log(' - Benefits: Reusable across all tools, cleaner main flow');
console.log(' - Complexity reduction: -1');
console.log(' - Line reduction: ~8 lines');
console.log('\n2. Format Conversion Helper:');
console.log(' - formatConvertedTime(date, timezone, customFormat, defaultFormat)');
console.log(' - Benefits: Simplifies format handling logic');
console.log(' - Complexity reduction: -1');
console.log(' - Line reduction: ~6 lines');
console.log('\n3. Build Result Helper:');
console.log(' - buildConversionResult(original, converted, fromOffset, toOffset, difference)');
console.log(' - Benefits: Consistent result building, easier to extend');
console.log(' - Complexity reduction: 0');
console.log(' - Line reduction: ~7 lines');
console.log('\n4. Error Handler Helper:');
console.log(' - handleConversionError(error, format)');
console.log(' - Benefits: Centralized error handling, reusable');
console.log(' - Complexity reduction: -2');
console.log(' - Line reduction: ~12 lines');
console.log('\nRecommended Phase 4 Plan:');
console.log('1. Extract handleConversionError() - Most complexity reduction');
console.log('2. Extract formatConvertedTime() - Simplifies format logic');
console.log('3. Extract cache helpers if needed for line count');
console.log('\nExpected Final State:');
console.log('- Complexity: 8-9 (well under limit)');
console.log('- Lines: 40-45 (well under limit)');
console.log('- Benefits: Reusable helpers for other tools');
