About Hex Timestamps
What are hex timestamps?
- • Unix timestamps represented in hexadecimal
- • Common in embedded systems and firmware
- • Used in binary file formats and protocols
- • More compact than decimal representation
Endianness matters:
- • Big Endian: Most significant byte first
- • Little Endian: Least significant byte first
- • x86/x64 systems typically use little endian
- • Network protocols typically use big endian
Examples:
Current Unix: 1759386644
Big Endian Hex: 0x68DE1C14
Little Endian Hex: 0x141CDE68
Fun fact:The Unix timestamp 0x7FFFFFFF (2147483647) is the famous "Year 2038 problem" for 32-bit systems - January 19, 2038 at 03:14:07 UTC!
