Frequently asked questions
Seconds or milliseconds?
Ten digits is seconds, thirteen is milliseconds. JavaScript uses milliseconds; most servers use seconds.
What is the year 2038 problem?
Systems storing Unix time in a signed 32-bit integer overflow on 19 January 2038. Modern 64-bit systems are fine.
Is my data uploaded anywhere?
No. Everything runs in your browser with JavaScript — nothing you type or open is sent to our servers.
