About the Unix Timestamp Converter
Unix time (also called epoch time or POSIX time) is a system for describing a point in time as a single integer — the number of seconds elapsed since the Unix Epoch: 1 January 1970, 00:00:00 UTC. It is used ubiquitously in programming, databases, APIs, and log files.
Seconds vs Milliseconds
Most Unix timestamps are in seconds (10 digits for dates after 2001). JavaScript and many APIs use milliseconds (13 digits). This tool automatically detects which format you've entered and converts both.
