Overview

Convert a calendar date and wall-clock time into Unix epoch values in seconds, milliseconds, microseconds, and nanoseconds. An explicit IANA timezone makes the UTC instant clear before the numeric value is generated.

How It Works and Key Features

Choose a date, optionally enter seconds in the time field, select the timezone that owns that wall time, and review the selected-zone, UTC, and ISO 8601 results. The tool then exposes four epoch precisions for different runtimes and storage systems.

Examples and Use Cases

Create API expiration values, schedule background jobs, seed database fixtures, or compare a local incident time with server logs. For example, 2024-01-01 00:00:00 in UTC becomes 1704067200 seconds.

Edge Cases and Limitations

A date without a time is treated as midnight in the selected zone. DST gaps or repeated wall times can be ambiguous, and the browser IANA database determines the resolved offset. Microsecond and nanosecond values are scaled from millisecond precision and do not add real sub-millisecond accuracy.
