Question 1

What is a Unix timestamp?

Accepted Answer

A Unix timestamp is the number of seconds (or milliseconds) since 1970-01-01T00:00:00Z. It is timezone-independent until you format it for display.

Question 2

How do I convert a timestamp to a date?

Accepted Answer

Paste a Unix timestamp, ISO-8601 string, or use the current time. The converter shows UTC and local representations you can copy.

Question 3

Does ByteToolBox upload timestamps I convert?

Accepted Answer

No. Conversion runs locally in your browser. Values are not sent to ByteToolBox servers.

Question 4

Seconds or milliseconds?

Accepted Answer

Values around 10 digits are usually seconds; 13 digits are usually milliseconds. Mixing them shifts dates by orders of magnitude — check the magnitude before converting.

Question 5

Does this support ISO-8601 and timezones?

Accepted Answer

Yes. You can convert between Unix time, ISO-8601, and human-readable dates, including UTC and timezone-aware display.
