Frequently asked questions

Does it handle milliseconds?

Yes — it auto-detects whether your timestamp is in seconds or milliseconds and converts correctly.

What formats can I paste for a date?

Most common formats work — ISO (2025-01-15T14:30), '2025-01-15 14:30', or 'Jan 15 2025'.

Is it accurate to my timezone?

Local time uses your device's timezone; UTC and ISO are also shown.
