Frequently asked questions
Seconds or milliseconds — how do I know?
The tool auto-detects: 10-digit values are treated as seconds, 13-digit as milliseconds. Both interpretations are shown so you can never misread.
Which timezone is used?
Results show your local timezone and UTC side by side, so there is never ambiguity.
What is the Unix epoch?
January 1, 1970 00:00:00 UTC — the zero point from which Unix time counts seconds. Timestamps before it are negative.
