FAQ
What is a Unix timestamp?
The number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC — the "Unix epoch". It's the standard way computers store and compare time, independent of time zones.
How do I know if my timestamp is in seconds or milliseconds?
This tool auto-detects: values above 10¹¹ are treated as milliseconds. As a rule of thumb, current timestamps in seconds have 10 digits; in milliseconds, 13.
Which time zone is "Local"?
Whatever time zone your device is currently set to. The UTC row always shows the same moment in Coordinated Universal Time, so you can compare across zones.
What happens in 2038?
Systems storing timestamps as 32-bit signed integers overflow on January 19, 2038. Modern 64-bit systems are unaffected — this tool handles dates far beyond 2038 correctly.
