Common questions
What limitations apply?
Dates entered here are interpreted as UTC. Output also labels your browser’s local timezone. Leap seconds are not represented.
Is my input saved?
No. It stays in browser memory and clears on refresh. Successful actions record only a stable tool ID and name, never your entered data.
