FAQ

Seconds or milliseconds — how do I tell?
Timestamps that are 10 digits long are seconds (since 1970). 13-digit numbers are milliseconds. The tool auto-detects but you can override.
What is the Unix epoch?
The Unix epoch is 00:00:00 UTC on 1 January 1970. Unix timestamps count the seconds elapsed since that moment, ignoring leap seconds.
