Unix timestamp converter
Time
Paste any Unix timestamp (seconds or milliseconds) or ISO 8601 date. The tool detects the format and shows all common interpretations side by side, in UTC, your local timezone, and any IANA zone.
Input
Enter a timestamp or ISO 8601 date.
Numeric inputs are auto-detected: 10-digit values are read as seconds, 13-digit values as milliseconds. Anything non-numeric is parsed via the browser's Date constructor, which accepts ISO 8601 and most RFC 2822 forms.
