Timestamp Converter — ISO 8601, Unix, UTC
Convert between ISO 8601, Unix timestamps, UTC, and human-readable date formats. Supports seconds and milliseconds.
What is ISO 8601?
ISO 8601 is the international standard for representing dates and times. Format: YYYY-MM-DDTHH:mm:ss.sssZ. It is widely used in APIs, databases, and log files because it is unambiguous and sortable.
Unix Timestamp vs ISO 8601
A Unix timestamp is the number of seconds since January 1, 1970 (UTC). It is compact but not human-readable. ISO 8601 is human-readable but longer. Both are commonly used in APIs and databases.
