Hex & Binary Tools
MS-DOS Date/Time Converter
Encode or decode the packed 16-bit MS-DOS date and time fields used by formats such as ZIP.
Tool family
Inspect bytes, numbers, endian order, signatures, and low-level data.
Current catalog
Planned and deprecated records are intentionally excluded from Tool Family archives. Each result still carries its own support and processing state.

Compatibility first
A tool family groups related jobs, but individual file formats and game versions can have different requirements. The individual tool page is the source of truth for compatibility, processing mode, limitations, and verification details.
