Frequently Asked Questions

Does it automatically detect seconds vs milliseconds?

Yes. In Auto-detect mode, magnitudes under 100 billion are parsed as seconds, values from 100 billion to 100 trillion as milliseconds, and larger values as microseconds—or you can lock precision manually.

What is the Unix Epoch?

The Unix epoch counts elapsed seconds since 1970-01-01T00:00:00Z (UTC), excluding leap seconds.
