Unix Timestamp — Complete Reference

The Unix timestamp (epoch time) is the number of seconds since January 1, 1970, 00:00:00 UTC. It is the universal standard for time representation in software — used in databases, APIs, log files, JWT tokens, signed URLs, and virtually every backend system. Our converter handles both second-precision (10-digit) and millisecond-precision (13-digit) timestamps automatically.

Common Uses of Unix Timestamps

  • JWT tokens — the exp and iat fields in JWT payloads are Unix timestamps
  • Signed URLs — S3 presigned URLs and CDN signed URLs use epoch expiry
  • Database storage — timestamps stored as integers are timezone-agnostic and sortable
  • Log analysis — nginx, Apache, and syslog events carry epoch timestamps
