What Is a Unix Timestamp?
A Unix timestamp counts the number of seconds (or milliseconds) that have elapsed since January 1, 1970, 00:00:00 UTC (the Unix epoch). It is timezone-independent by design, which is why it is the standard way databases, APIs, and log files store points in time.
Common Uses
- Debugging
created_at/updated_atfields returned by an API. - Converting log timestamps to a readable date for incident analysis.
- Calculating the timestamp for a scheduled job or token expiry.
