Timestamp Converter

Overview

Convert copied timestamp values from logs, APIs, databases, webhooks, analytics exports, and generated test data. You can switch between timestamp-to-date, date-to-timestamp, and current timestamp modes without uploading input after the page loads.

Best for

• Converting Unix timestamp seconds or milliseconds into readable dates.
• Checking whether an epoch value is seconds, milliseconds, microseconds, or nanoseconds.
• Turning a local date-time into Unix seconds, milliseconds, microseconds, or nanoseconds.
• Copying timestamp values for API docs, QA notes, logs, issue reports, and fixtures.

Not for

• Legal timestamp evidence, signed audit records, time synchronization, or server clock verification.
• Timezone database research, recurring schedules, cron rules, leap-second analysis, or calendar invites.

How it works

1. Choose timestamp to date, date to timestamp, or current timestamp.
2. Pick the unit: seconds, milliseconds, microseconds, or nanoseconds.
3. Review UTC time, browser local time, and common Unix units together.

Limits and privacy

The converter uses JavaScript Date support in the browser. Date display is millisecond precision, so microsecond and nanosecond inputs are truncated when shown as a date.

Common uses

• Decode a timestamp from an API response or log line.
• Convert a webhook created_at value into a readable date.
• Create a Unix timestamp for test fixtures or documentation.
• Compare seconds and milliseconds when a pasted timestamp looks too large or too small.

Useful facts

• Tiny Work Tools Timestamp Converter runs locally in the browser.
• It shows UTC time, local browser time, Unix seconds, milliseconds, microseconds, and nanoseconds.
