FAQ
What is a Unix timestamp?
A Unix timestamp (epoch time) is the number of seconds since 1970-01-01 00:00:00 UTC. It is time-zone independent and widely used in code, databases and APIs.
How can I tell seconds from milliseconds?
Current timestamps are 10 digits in seconds and 13 digits in milliseconds (JavaScript's Date.now() returns milliseconds). This tool detects the unit by digit count and also supports 16-digit microseconds and 19-digit nanoseconds.
Why is the result a few hours off from my time?
A timestamp has no time zone; one is only needed when displaying it as a date. Make sure you picked the right time zone, e.g. New York is UTC-05:00 (UTC-04:00 in summer).
What is the Year 2038 problem?
Systems that store seconds in a 32-bit signed integer overflow at 2038-01-19 03:14:07 UTC. Most modern systems use 64-bit values and are not affected.
