What is a Unix timestamp?
A Unix timestamp is the number of seconds (or milliseconds) since January 1, 1970, 00:00:00 UTC. Used widely in databases and APIs.
What is ISO 8601 format?
ISO 8601 is a standard date format: YYYY-MM-DDTHH:MM:SSZ. Used for APIs, JSON, and international date representation.
What's the difference between seconds and milliseconds?
Unix seconds count since 1970 (1-second resolution). Milliseconds are 1000x larger (millisecond resolution). JavaScript uses milliseconds by default.

Can I get the current time?
