Questions
Why are some numbers treated as milliseconds?
A current time in seconds is about 1.7 billion. A current time in milliseconds is about 1.7 trillion. 100 billion sits between them, so it is a practical cut.
Which timezone is the date field?
The timezone of this computer. UTC is shown separately as an ISO time ending in Z.
