Convert Unix timestamps to human-readable dates and vice versa. Supports seconds and milliseconds with timezone selection.
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC (the Unix epoch). It's widely used in programming and databases.
Unix timestamps in seconds are 10 digits (e.g., 1700000000), while milliseconds timestamps are 13 digits (e.g., 1700000000000). JavaScript's Date.now() returns milliseconds.
Yes, the tool shows the timestamp in both UTC and your local timezone, making it easy to convert between different time representations.
