FAQ
What is Unix epoch time?
Unix epoch time is the number of seconds that have elapsed since January 1, 1970 (midnight UTC). It is widely used in programming for storing and comparing dates.
What is the difference between seconds and milliseconds?
Unix timestamps in seconds are 10 digits (e.g., 1700000000). Millisecond timestamps are 13 digits (e.g., 1700000000000). JavaScript uses milliseconds, while most Unix systems use seconds.
Does this handle negative timestamps?
Yes. Negative timestamps represent dates before January 1, 1970. For example, -86400 represents December 31, 1969.
What timezone is used for conversion?
The local time shown uses your browser timezone. UTC and ISO 8601 formats are also displayed for timezone-independent reference.
