Current Timestamp Generator

About this tool

Get the current time in multiple formats at once: Unix timestamp (seconds), milliseconds, and ISO 8601. Click to refresh to the current moment.

Example

Input: (now)

Output: Unix: 1718000000, ISO: 2024-...

This tool runs entirely in your browser. Your data is processed locally and never uploaded to a server.

How to use this tool

1. Open the Timestamp Generator page and look at the current values shown for seconds, milliseconds, and ISO 8601.
2. Use the Unix seconds value when you need a compact timestamp for logs or APIs that expect seconds since the epoch.
3. Use the milliseconds value when your system needs higher precision or stores time in millisecond format.
4. Copy the ISO 8601 value when you need a readable, standard datetime string for sharing or configuration.
5. Click refresh whenever you want a new timestamp for the exact current moment.

Step by step, what happens

1. The tool reads the current system time at the moment you open it or refresh it.
2. It converts that same moment into three common formats: Unix seconds, Unix milliseconds, and ISO 8601.
3. It displays all three values together so you can compare formats without doing manual conversion.
4. When you click refresh, it repeats the process and updates every value to the new current time.

Worked example

Suppose you need a current timestamp to paste into an API request and a log entry.

Input: refresh

1. You click refresh to capture the current moment.
2. The tool updates the Unix seconds, Unix milliseconds, and ISO 8601 values for that moment.
3. You copy the format that matches your target system, such as seconds for an API or ISO 8601 for a readable timestamp.

Tips and common mistakes

• Use Unix seconds for systems that expect a simple integer timestamp, but use milliseconds if the target explicitly asks for them.
• Do not add or remove digits when copying the Unix values, since seconds and milliseconds are easy to mix up.
• If you need the exact current time, refresh right before copying because the displayed values change from moment to moment.
• ISO 8601 is usually the safest choice when you want a format that is clear to humans and widely accepted by software.
