About this tool.
A Unix timestamp counts the seconds since 1 January 1970 at 00:00:00 UTC, known as the epoch. Databases, logs, JWT tokens and APIs store times this way because a single number has no timezone or format ambiguity.
Paste a timestamp and this tool decides whether it is in seconds or milliseconds, then shows ISO 8601, UTC and your local time. You can also pick a date and get the matching timestamp.
Three steps, then you are done.

Paste a timestamp, or choose a date and time.
