Convert timestamps with context

Unix timestamps are the lingua franca of distributed systems. This converter translates raw epoch values into human-readable dates, handles milliseconds, and reconciles timezones so you can audit logs or craft cron jobs without mental math.

From epoch to calendar

Paste seconds or milliseconds since 1 January 1970 and instantly view the UTC and local-time equivalents. Toggle between ISO 8601 strings, RFC 2822 formats, or friendly text for status updates. The converter flags values that overflow 32-bit limits, helping you prepare for the 2038 rollover in legacy systems.

Need the current timestamp? One click copies it to your clipboard along with handy code snippets for JavaScript, Python, PHP, Go, and Ruby so teammates know how to generate the same value inside their stack.

Bidirectional support
Enter a date to receive the corresponding epoch value, perfect for seeding databases or building comparison queries.
Timezone awareness
Switch between local time, UTC, or any IANA timezone to avoid daylight-saving surprises.

Debugging made simple

Observability pipelines and audit logs often record timestamps as integers. Drop those numbers here to understand when an incident occurred, then annotate the result with context you can share in incident reports.

Because calculations run locally, you can investigate sensitive customer data or compliance events without leaving your secure environment.

Relative deltas
View how many minutes or days separate two timestamps to spot gaps in job schedules or webhook processing.
Y2K38 warnings
Clear messaging alerts you when 32-bit systems would overflow, prompting you to prioritize migrations.

Popular workflows

Log forensics

Convert timestamps from stack traces so you can align them with human-readable timelines during postmortems.

Release planning

Compute freeze windows or maintenance schedules by translating local dates into epoch values consumed by CI.

Database seeding

Generate fixed timestamps for fixture files without writing throwaway scripts.

Cron validation

Check how upcoming cron expressions line up against real-world dates.

Next step

Design the job schedule afterward

Feed the converted timestamps into the Cron Generator to build readable, copy-ready schedules for Kubernetes, Linux, or cloud task runners.

Frequently asked questions

What is a Unix Timestamp?

A Unix timestamp (or Epoch time) is the number of seconds that have elapsed since January 1, 1970 (UTC), not counting leap seconds. It is widely used in computer systems to track time in a format that is independent of timezones.

How do I handle timezones with this converter?

Our converter automatically detects your local timezone and displays the date relative to it. You can also view the UTC (Coordinated Universal Time) equivalent. The Unix timestamp itself is timezone-agnostic—it represents a specific point in time regardless of location.

What is the Year 2038 problem?

The Year 2038 problem relates to 32-bit systems that store time as a signed integer. On January 19, 2038, these counters will overflow, potentially causing systems to interpret the date as 1901. Modern 64-bit systems (and this tool) handle dates well beyond 2038 without issues.

Does this tool send my data to a server?

No. All conversions happen entirely within your browser using JavaScript. Your data never leaves your device, ensuring privacy and speed.

Can I convert milliseconds?

Yes. If you enter a 13-digit number, the tool automatically detects it as milliseconds. You can also explicitly choose between seconds and milliseconds output modes.

How to use Unix Timestamp Converter

Follow these four quick steps to translate timestamps without losing context right inside your browser—no downloads, no accounts, and no data leaving the FreeTools.run sandbox.

Step 1: Load your source data
Paste text, drag a file, or start with our curated sample to understand how the datetime workflow behaves with real inputs.
Step 2: Adjust tool options
Toggle presets, update formatting rules, or choose export preferences. All controls update in real time so you can preview the effect before committing.
Step 3: Review the live preview
Use the split-pane preview, inline validation, or diff output to confirm the transformation looks correct before you copy anything back into your project.
Step 4: Export or chain another tool
Copy the result, download a file, or jump into a related FreeTools.run utility (like Diff Checker or the QR Code Generator) to continue the workflow without leaving the browser.
