Frequently Asked Questions (FAQ)
What is a Unix epoch timestamp?
A Unix timestamp is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds.
How do I distinguish seconds and milliseconds timestamps?
Seconds timestamps are 10 digits long (e.g., 1780000000), while milliseconds timestamps are 13 digits long (e.g., 1780000000000), containing finer sub-second precision.
Does this tool require an internet connection?
No. All timezone offsets and date conversions are performed in the browser client memory, making it fast and completely secure.
