Question 1

What is a UNIX timestamp?

Accepted Answer

A UNIX timestamp is the number of seconds (or milliseconds) elapsed since 00:00:00 UTC on 1 January 1970, not counting leap seconds.

Question 2

What’s the difference between seconds and milliseconds?

Accepted Answer

Seconds timestamps are 10-digit values (e.g., 1726200000). Milliseconds timestamps are 13-digit values (e.g., 1726200000000). The tool auto-detects and converts both.

Question 3

Does the converter handle time zones and DST?

Accepted Answer

Yes. You can view times in UTC, your local time, or a chosen IANA time zone. Conversions are DST-safe and leap-year aware.

Question 4

Can I convert ISO 8601/RFC 3339 strings?

Accepted Answer

Yes. Paste an ISO/RFC string and the tool will parse it into epoch and formatted outputs in multiple zones.

Question 5

Is my data uploaded anywhere?

Accepted Answer

No. The converter runs locally in your browser. Nothing is sent to a server unless you export to a file on your device.
