FAQ
What is a Unix timestamp?
A Unix timestamp is the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC. It is timezone-independent and widely used in APIs and databases.
What is the difference between seconds and milliseconds?
A 10-digit timestamp is in seconds. A 13-digit timestamp is in milliseconds. This tool auto-detects the format based on the number of digits.
How is the local time calculated?
