Developer debugging
Timestamps appear in API responses, database rows, event logs, cookie expirations, and scheduled tasks.
ISO output
ISO 8601 output is useful because it includes a clear date, time, and UTC marker that is easy to compare across systems.

This tool converts values exactly as entered. It does not infer leap seconds, historical calendar rules, or business time zones.
Timestamp FAQ
Why is my result in 1970?
You may have pasted milliseconds while the selector is set to seconds, or entered a very small timestamp value.
What does the Z mean in ISO time?
The Z suffix means UTC time. It is commonly used in server logs and API timestamps.
Does this account for my timezone?
The local time line uses your browser timezone. The UTC and ISO lines are independent of your local timezone.
