Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds since January 1, 1970, 00:00:00 UTC. It's widely used in programming and databases because it's timezone-independent.
Does it account for leap years?
Yes. Date calculations correctly handle leap years, varying month lengths, and daylight saving time transitions.
What is ISO 8601?
ISO 8601 is an international standard for date/time formatting (e.g., 2024-03-15T14:30:00Z). The Z suffix indicates UTC timezone.
