Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (or epoch time) is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. It is a widely used standard for representing points in time in programming, databases, and APIs.
How do I know if my timestamp is in seconds or milliseconds?
Timestamps in seconds are typically 10 digits long (e.g., 1700000000), while millisecond timestamps are 13 digits (e.g., 1700000000000). Our converter auto-detects the format based on the number of digits.
Does the converter account for daylight saving time?
Yes. When you select a specific timezone, the converter uses your browser's built-in timezone database, which includes all historical and current daylight saving time rules.
