FAQ
What is a Unix timestamp?
It is the number of seconds elapsed since 1 January 1970 00:00:00 UTC (the Unix epoch). Databases, APIs, and log files use it because it is a single sortable number with no time zones or daylight saving to worry about.
How do I tell seconds from milliseconds?
The calculator auto-detects it: timestamps of roughly 13+ digits are treated as milliseconds (JavaScript style) and divided down, while 10-digit values are read as seconds.
When does the 32-bit timestamp overflow?
On 19 January 2038 a signed 32-bit counter runs out of seconds — the famous Year 2038 problem. Modern 64-bit systems are unaffected, so new code simply stores timestamps in 64-bit integers.
