Code Review
This pull request refactors the DateTime struct to use derived implementations for Ord and PartialOrd, replacing the previous handwritten ones. This is a solid improvement, leveraging the lexicographical ordering of the MS-DOS date and time formats when packed into integers. This change correctly simplifies the code and improves comparison performance by replacing a sequence of expensive field extractions and comparisons with two simple integer comparisons. The logic is sound and the implementation is clean. I have no issues to report.
Use the derive macro to implement these.

Thanks; hopefully now it compiles down to a u32 comparison. |
Use the derive macro to implement these.
In #267, I changed these to handwritten implementations. However, given the structure of MS-DOS date and time, I don't think this change was necessary.
