FAQ
What is a Unix timestamp?
The number of seconds since 1 January 1970 00:00 UTC. Computers use it everywhere because it does not depend on a time zone.
Why are some timestamps 13 digits long?
They count milliseconds (JavaScript and Java do). Ten digits is seconds. The tool detects the unit from the size.
Is Bangkok UTC+7 all year?
Yes, Thailand has no daylight saving. The tool uses your browser's IANA time-zone database, which handles other countries' daylight saving correctly.
