Epoch Converter auto-detects the input format (epoch seconds, epoch milliseconds, ISO 8601, RFC 2822, human-readable, or relative phrases like "3 days ago") and returns all common date formats simultaneously. Multi-timezone output converts to multiple IANA zones in one call with DST awareness and UTC offset for each zone.

FAQ

What is a Unix epoch timestamp?

The number of seconds (epoch-s) or milliseconds (epoch-ms) elapsed since January 1, 1970 UTC. It is the universal reference timestamp used in databases, log files, and APIs because it is unambiguous and time-zone-independent.

How does the tool detect seconds vs milliseconds?

Numeric values with 13 digits are treated as milliseconds (modern JavaScript Date). 10 digits are treated as seconds (Unix convention). The tool returns both epoch and epochMs in every response so downstream code can pick the format it needs.

What IANA timezone names are supported?

All names from the IANA Time Zone Database (tz database). Examples: America/New_York, America/Los_Angeles, Europe/London, Asia/Tokyo, Australia/Sydney, UTC. Three-letter abbreviations (EST, PST) are not supported because they are ambiguous around DST transitions.

Can I use this tool via the MCP API?

Yes. The tool is registered on the obfus.link MCP server at https://obfus.link/mcp. Call it from any MCP-compatible agent with a Shared Payment Token. The MCP tool name matches the snake_case slug shown in the integration snippet.
