Timestamp Converter
Convert Unix timestamps and date strings into readable time formats.
What this tool does
Convert Unix seconds, Unix milliseconds, or date strings into UTC, local time, and normalized timestamp output so you can debug event timelines and API payloads quickly.

Example output
{
"input": "1710000000",
"unixSeconds": 1710000000,
"unixMilliseconds": 1710000000000,
"utc": "2024-03-09T16:00:00.000Z"
}Step-by-step instructions
- Paste a Unix timestamp (seconds or milliseconds) or a date string.
- Click Transform to convert it.
- Review UTC, local time, and Unix equivalents.
Common use cases
- Converting Unix timestamps in logs to readable time.
- Debugging event-order issues across services and timezones.
- Checking API payload dates in UTC and local time.
Useful for debugging API payloads, logs, analytics events, and systems that store Unix timestamps.
Common mistakes to avoid
- Confusing Unix seconds with Unix milliseconds.
- Comparing values across systems without checking timezone context.
- Assuming ambiguous date strings parse the same way in every environment.
Frequently Asked Questions
How does Timestamp Converter detect seconds vs milliseconds?
It inspects numeric length and converts both representations into normalized UTC and local-time values.
Does Timestamp Converter show UTC and local time?
Yes. It returns UTC output and local-time output so timezone offsets are clear.
Does it support seconds and milliseconds?
Yes, both Unix seconds and milliseconds are supported.
Can I convert date strings too?
Yes, standard date strings can be parsed and converted.
Why do local and UTC values differ?
Local time includes your timezone offset, while UTC is timezone-neutral.
What input format does Timestamp Converter expect?
Use the format shown in the example input on this page.
What does Timestamp Converter output?
It returns transformed output that you can copy directly from the result panel.
Why might Timestamp Converter return an error?
A common issue is: Confusing Unix seconds with Unix milliseconds.
