What is a Hex Timestamp?
A hex timestamp is simply a Unix timestamp (seconds since the epoch) written in base-16 instead of base-10. The underlying value is identical — only the text representation changes.
You'll most often see this format in DHCP lease files (like Linux's dhcpd.leases), some embedded systems, and low-level binary log formats where hex is more compact or matches the surrounding data.
- Same value as a Unix timestamp, just base-16
- Case-insensitive —
