Quick FAQ
What is a Unix timestamp?
It’s the number of seconds (or milliseconds) since 1970-01-01 00:00:00 UTC. Many systems store time this way because it’s compact and sortable.
How do I tell seconds from milliseconds?
Seconds are usually 10 digits; milliseconds are usually 13. If your converted date looks wildly wrong, you likely selected the wrong unit.
Why does time zone matter?
Epoch is defined in UTC, but you may want to view the time in local time for user-facing debugging. Comparing both helps avoid misreads.
Key benefits
- Use unix timestamp converter for quick developer tools tasks when you need an answer or conversion immediately.
- It works well for one-off jobs, repeat workflows, and high-intent utility searches where speed matters more than a full app.
- Because ConvertPal is no-login, users can open the tool, do the task, and move on without account friction.
What this tool does
The Unix Timestamp Converter translates between epoch timestamps and readable date/time formats (like ISO 8601). It’s built for developers, analysts, and support teams who debug logs, APIs, databases, and event pipelines where time is stored as an integer. Related utilities on ConvertPal include JWT Decoder, JSON Formatter, and Minutes to Hours.
A common pitfall is mixing seconds and milliseconds: some systems store epoch in seconds (10 digits) while others use milliseconds (13 digits). Converting with the wrong unit can make dates appear in 1970 or far in the future. This tool helps you confirm the unit quickly and convert accurately.
Use it when you’re investigating incidents (“when did this event happen?”), building integrations (“what timestamp should I send?”), or validating exports where time zones and units can cause subtle bugs.
How to use it
- Paste the Unix timestamp from your log, API response, or database row.
- Select seconds vs milliseconds (or confirm the inferred unit).
- Convert to see a human-readable date/time (typically including UTC).
- Enter a date/time to generate an epoch value for requests or tests.
- Copy the result into your code, query, or incident notes.
More context
Off-by-1000 errors (seconds vs ms) are one of the most common causes of broken expiry logic—double-check the raw number as well as the converted date.
