Seconds (or ms) since Jan 1, 1970 00:00:00 UTC. Standard for dates in APIs and databases.
What is Jan 1, 1970 UTC?
Unix epoch—the reference date for timestamps. Used as origin in many programming languages.
Milliseconds vs seconds?
1 second = 1000 ms. Date.now() returns ms; many APIs use seconds. 10 digits = seconds, 13 digits = ms.
How to convert timestamp to datetime?
