Why does my timestamp produce a date far in the future?
The most common cause is treating milliseconds as seconds or seconds as milliseconds. Check the unit used by the source system.

Frequently Asked Questions
Does the timestamp itself contain a time zone?
An epoch timestamp identifies an instant. The human-readable clock time you see depends on the time zone used to display that instant.
Is a Unix timestamp the same thing as an ISO 8601 date?
No. They can represent the same moment, but Unix time is numeric epoch-based data while ISO 8601 is a formatted date-time representation.
