Frequently asked questions
Should I paste seconds or milliseconds?
Either. The tool auto-detects the unit, converts it to a readable date in your local timezone and UTC, and can also turn a picked date back into a timestamp.
Which timezones are shown?
Your device's local time and UTC side by side, so you never have to convert mentally. A live clock also shows the current Unix time.
Is anything sent to a server?
No. All conversion uses your browser's Date handling locally.
