Unix Timestamp Converter
What is a Unix timestamp?
It's the number of seconds since 1970-01-01 00:00:00 UTC (the 'epoch'). It's a compact, timezone-free way to store an instant in time.
Seconds or milliseconds?
Unix timestamps are classically in seconds, but many systems (JavaScript, some APIs) use milliseconds. A 13-digit value is usually milliseconds; 10 digits is seconds.
What about timezones?
The epoch is always UTC. Convert to a local timezone only when displaying to users.
