FAQ
Seconds or milliseconds?
This tool expects seconds, the standard on-chain. If your number has 13 digits it is milliseconds, so drop the last three.
Why do chains use Unix time?
It is a single unambiguous integer, immune to time zones and daylight saving, which matters when nodes worldwide must agree.
