What is a Unix timestamp?

A 10-digit or 13-digit integer representing total seconds or milliseconds elapsed since January 1, 1970, 00:00:00 UTC.

What is the Unix Epoch?

The reference point defined as 00:00:00 UTC on 1 January 1970.

How do I tell if a timestamp is in seconds or milliseconds?

10-digit numbers represent seconds; 13-digit numbers represent milliseconds.

What is the Year 2038 problem (Y2K38)?

On Jan 19, 2038, 32-bit signed integers will wrap around to negative numbers, resetting dates to 1901 unless updated to 64-bit.

Does Unix time account for leap seconds?

No, Unix time repeats timestamp integers during leap seconds.

Are my timestamps sent to ScanSuite servers when converting?

No. All conversion logic runs locally in your client browser memory.

How do I convert a Unix timestamp in JavaScript?

Use `new Date(timestamp * 1000).toUTCString()` for seconds or `new Date(timestamp)` for milliseconds.

How do I get current Epoch time in Linux CLI?

Run `date +%s` for seconds or `date +%s%3N` for milliseconds.

How do I convert Unix timestamps in SQL (PostgreSQL / MySQL)?

In PostgreSQL use `to_timestamp(epoch)`; in MySQL use `FROM_UNIXTIME(epoch)`.

What is ISO 8601 format?

An international date formatting standard formatted as `YYYY-MM-DDTHH:mm:ss.sssZ`.

Why is GMT and UTC practically the same for epoch conversion?

GMT is a time zone while UTC is a time standard, but both share the same reference time offset (+00:00).

Can I convert negative Unix timestamps for dates before 1970?

Yes, negative integer timestamps represent dates prior to January 1, 1970.

How do I convert Python timestamps?

Use `datetime.fromtimestamp(epoch, tz=timezone.utc)` in Python.

Is this timestamp converter free without usage limits?

Yes, ScanSuite provides free, unlimited browser-based timestamp conversions.

What precision does this tool support?

Supports both seconds (10-digit) and milliseconds (13-digit) precision.

Why does local time output differ depending on where I am?

Local time adjusts for your computer's configured system time zone and daylight saving rules.

How do I copy current Epoch time quickly?

Click the live ticker button at the top of the converter to copy current Epoch seconds or milliseconds.

What is epoch time in Excel or Google Sheets?

Excel uses 1900 as its reference epoch; convert Unix epoch in Excel using `=(epoch / 86400) + DATE(1970,1,1)`.

Free Unix Timestamp Converter & Epoch Calculator

A Unix timestamp converter converts between Unix epoch time (the total number of seconds elapsed since 00:00:00 UTC on January 1, 1970) and human-readable calendar dates across UTC, GMT, and local time zones.

Paste any 10-digit (seconds) or 13-digit (milliseconds) Unix timestamp to view instant conversions in UTC and local time, or select a date/time to generate the exact Epoch timestamp with live current time tracking.

Unix timestamp (also known as Epoch time or POSIX time) measures time as a single continuous integer representing seconds elapsed since 00:00:00 UTC on January 1, 1970, ignoring leap seconds.

ScanSuite's free online timestamp converter allows developers, database administrators, and system engineers to convert between Unix timestamps and human-readable date formats in real time. Switch seamlessly between seconds and milliseconds precision with full support for local time zones, UTC, and ISO 8601 standards across past and future dates.

ScanSuite's free Unix timestamp converter converts between Epoch time and human dates across UTC, local time, and ISO-8601. With a live current ticker and auto precision detection, developers can debug timestamps effortlessly.
