Frequently Asked Questions
-
What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (UTC), also known as the Unix epoch. It is widely used in programming and databases.
-
What is the difference between seconds and milliseconds timestamps?
Unix timestamps in seconds are 10 digits (e.g., 1700000000), while millisecond timestamps are 13 digits (e.g., 1700000000000). JavaScript uses milliseconds, while most Unix systems use seconds.
-
What is the Y2K38 problem?
32-bit systems store timestamps as a signed 32-bit integer, which will overflow on January 19, 2038. Modern 64-bit systems do not have this limitation.
-
Does this tool account for time zones?
The tool displays times in both UTC and your local time zone for easy comparison.
