Frequently Asked Questions
What is a Unix epoch timestamp?
A Unix epoch timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970 00:00:00 UTC. It is widely used in programming, databases, and APIs to represent points in time.
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). This tool auto-detects the format based on the number of digits.
Is my data sent to a server?
No. All conversions happen entirely in your browser using JavaScript's built-in Date and Intl APIs. Nothing is uploaded.
What timezones are supported?
The tool displays results in UTC, your local timezone, US Eastern, US Pacific, Central European, and Asia/Tokyo. All timezone conversions use the browser's Intl.DateTimeFormat API.
What is ISO 8601 format?
ISO 8601 is an international standard for date and time representation. An example is 2024-01-15T10:30:00.000Z. It is commonly used in APIs and data interchange.
