Questions
Is my text sent anywhere?
No. Everything runs in your browser and nothing you type or open is uploaded, logged or saved. Your settings are remembered on this device; your text isn't.
How is the unit detected?
Up to 11 digits is read as seconds, up to 14 as milliseconds, up to 17 as microseconds and anything longer as nanoseconds. That covers every date from 1973 to 5138 without guessing wrong.
What time zone does it use?
Timestamps are always UTC. The local time row uses your device's time zone. A date typed without a zone, like 2026-10-28 14:30, is read as your local time.
