About Date & Time Tools

Many file systems and binary logs store dates as a hex-encoded timestamp rather than a human-readable string. This category converts Unix timestamps to and from hexadecimal, so you can decode a raw timestamp or produce one for a binary format.

Frequently Asked Questions

Why store timestamps in hex?

A Unix timestamp is just a number of seconds since 1970; hex is a compact, fixed-width way to store or display that number in binary file formats.

What's the largest date a 32-bit hex timestamp can represent?

0x7FFFFFFF, which corresponds to January 19, 2038 — the well-known "Year 2038 problem" for systems still using 32-bit timestamps.
