FAQ
What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It's a standard way to represent time in computing systems.
What's the difference between seconds and milliseconds?
Unix timestamps can be in seconds (10 digits) or milliseconds (13 digits). Seconds is the standard format, while milliseconds provides more precision and is common in JavaScript.
How do I know if my timestamp is in seconds or milliseconds?
Generally, if your timestamp has 10 digits, it's in seconds. If it has 13 digits, it's in milliseconds. Timestamps around 1600000000 (seconds) represent dates around 2020.
Are the conversions adjusted for my timezone?
Yes, the local date/time formats show times in your browser's timezone. UTC formats show universal time, and ISO format includes timezone information.
Understanding Unix Timestamps
Unix timestamps are widely used in programming, databases, and APIs to represent time in a standardized format. They count seconds (or milliseconds) since the Unix epoch, making time calculations and comparisons straightforward across different systems and timezones.
