About this timestamp converter
Accepts Unix epoch values in seconds or milliseconds (auto-detected: 13+ digit values are treated as milliseconds) as well as ISO 8601 date strings. Output includes ISO/UTC/local renderings, both epoch units, and a relative description like “3 hours ago”.
Conversion uses your browser's own timezone database, runs locally, and works offline once the page is loaded.
