What is a Unix Timestamp?
A Unix timestamp counts time from January 1, 1970 at 00:00:00 UTC.
Seconds vs Milliseconds
Some systems store timestamps in seconds, while JavaScript and many logs use milliseconds. A millisecond timestamp is usually 13 digits; a second timestamp is usually 10 digits.
Why UTC Matters
Unix timestamps represent an absolute moment in time. Displayed local time can change by timezone, but the timestamp value points to the same moment.
