RSS feeds use RFC 2822. API responses use ISO 8601. Log files use whatever format the developer chose in 2008. User input arrives as &ldquo;next Tuesday at 3pm&rdquo; or &ldquo;2026年6月20日&rdquo;. A single misparsed date can cascade into missed alerts, duplicate billing cycles, or corrupted analytics. In a self-hosted data ingestion pipeline processing 100,000 documents per hour, even a 0.1% date parsing error rate means 100 corrupted records every hour.</p>
