Generate Random Unix Time
Create random Unix epoch timestamps within a range. Runs entirely in your browser, so your data never leaves your device.

How to use Generate Random Unix Time
- 1. Set the epoch range. Enter Minimum epoch (seconds) and Maximum epoch (seconds) to bound the random timestamps, using the same seconds-since-1970 values your system already stores.
- 2. Set the count and separator. Enter How many timestamps to generate and pick a Separator so the list pastes cleanly into a JSON array, spreadsheet column or SQL insert statement.
- 3. Copy the random timestamps. Copy the generated list of random Unix timestamps and use them as sample or test data wherever real epoch values are not yet available.
When to use Generate Random Unix Time
Generate Random Unix Time creates a list of unpredictable epoch timestamps within a range you set, useful anywhere a database, log or API test needs realistic-looking created_at or updated_at values. It saves writing a small script for a one-off need.
- Seeding a database table with varied timestamp columns. A test database looks more convincing when created_at values are spread across a plausible range rather than all identical. Generate random epochs within that range for the seed data.
- Fuzz-testing a timestamp-parsing function. Before shipping code that converts epoch seconds into readable dates, test it against a spread of random values including very old and very future timestamps. Generate the set here.
- Building mock API responses with realistic timestamps. A frontend under development needs a mock API that returns varied event timestamps instead of one repeated value. Generate random epochs and drop them into the mock response payload.
- Load-testing a time-series database with scattered data points. Benchmarking a metrics store works better with timestamps spread naturally across the target range rather than perfectly even intervals. Generate the random epochs to load as sample points.

About the Generate Random Unix Time tool
Generate Random Unix Time does its work locally, right in the browser. Create random Unix epoch timestamps within a range. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the Time Tools collection on EditSafely, a set of 90 small, focused Time utilities that share the same instant, private workspace.
You can shape the output with 4 settings, including Minimum epoch (seconds), Maximum epoch (seconds), How many timestamps and Separator, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Is Generate Random Unix Time free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Does the generator send anything to a server?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How do I get a different result?
Run the generator again. Each run is computed fresh on your device, and any options you change are applied to the next result immediately.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
