Questions
How does it tell seconds from milliseconds?
Numbers of 100,000,000,000 or more are read as milliseconds. In seconds that would be the year 5138, so nothing real is misread.
What is a Unix timestamp?
The number of seconds since 00:00:00 UTC on 1 January 1970, not counting leap seconds. It is the same everywhere in the world, regardless of time zone.
Which time zone is "local"?
Your browser’s time zone. The ISO 8601 row is always UTC.
