Epoch Format Guide
Epoch Format Guide: identify Unix timestamp precision from 10-, 13-, 16-, and 19-digit values.
Epoch Format Guide
Epoch timestamps represent elapsed time from a fixed starting point. Unix epoch uses 1970-01-01T00:00:00Z and is the most common format across APIs, operating systems, and databases.
Common Formats
| Format | Example | Precision | Best For |
|---|---|---|---|
| Unix seconds | 1700000000 | Seconds | APIs, databases, logs |
| Unix milliseconds | 1700000000000 | Milliseconds | JavaScript Date.now(), browser telemetry |
| ISO 8601 | 2023-11-14T22:13:20Z | Variable | Human-readable exchange format |
| RFC 3339 | 2023-11-14T22:13:20+00:00 | Variable | Web APIs and JSON payloads |
| Excel serial | 45244.9259259 | Fractional days | Spreadsheets and business exports |
Implementation Rules
- Store canonical timestamps in UTC.
- Document whether numbers are seconds, milliseconds, microseconds, or nanoseconds.
- Prefer ISO 8601 or RFC 3339 when people need to inspect values.
- Preserve timezone offsets at system boundaries, then normalize internally.

Epoch Format Guide: identify Unix timestamp precision from 10-, 13-, 16-, and 19-digit values.
Purpose
Use this tool to identify Unix timestamp precision from 10-, 13-, 16-, and 19-digit values. Key details: Unix precision commonly uses 10-digit seconds, 13-digit milliseconds, 16-digit microseconds, or 19-digit nanoseconds. Verify inputs, select a format or timezone, and copy accurate results for production workflows such as logs, APIs, databases, automation, and documentation.
Benefits
Review Unix precision at 10, 13, 16, or 19 digits for seconds through nanoseconds, catch malformed values, and copy reliable results. Browser processing keeps data on your device for repeatable checks. Use outputs in code, queries, tickets, and runbooks.
