Epoch & timestamp converter
Convert Unix time to dates and back, with automatic seconds-versus-milliseconds detection.
Epoch right now
ISO 8601 with Z or an explicit offset is safest. Date-only ISO values use UTC; date-times without an offset use your browser timezone. Conversion preserves milliseconds.

A note from experience: when a timestamp lands in 1970, someone sent seconds where milliseconds were expected. When it lands in the year 56000, the reverse. This tool states which it assumed so you can catch that.
