/**
 * @hixbe/time - Professional NTP Time Synchronization Package
 * 
 * A complete, production-ready TypeScript/JavaScript package for:
 * - Querying NTP servers
 * - Converting raw NTP timestamps to readable dates
 * - Analyzing NTP packet structure
 * - CLI tool for time synchronization
 * - Zero external dependencies
 * 
 * Main server: time.hixbe.com
 * Epoch support: NTP (1900) → Unix (1970) conversion
 * Precision: Microsecond accuracy
 * 
 * Usage Examples:
 * 
 * CLI:
 *   hixbe-time                          # Get current time
 *   hixbe-time --json                   # JSON output
 *   hixbe-time --verbose                # Detailed analysis
 *   hixbe-time --offset                 # Millisecond offset only
 *   hixbe-time --continuous             # Real-time monitoring
 *   hixbe-time --server pool.ntp.org    # Different server
 * 
 * TypeScript/JavaScript:
 *   import { NTPClient } from '@hixbe/time';
 *   const client = new NTPClient();
 *   const time = await client.getTime();
 *   const offset = await client.getOffset();
