⚠️ Potential issue | 🟡 Minor

Missing error check for GetTimeZoneInformation.

The return value of GetTimeZoneInformation is discarded. This function returns TIME_ZONE_ID_INVALID (0xFFFFFFFF) on failure, which should be checked to avoid returning zeroed/invalid timezone data.

Consider adding error handling:

 fn get_tz_info() -> TIME_ZONE_INFORMATION {
     let mut info: TIME_ZONE_INFORMATION = unsafe { std::mem::zeroed() };
-    unsafe { GetTimeZoneInformation(&mut info) };
+    let result = unsafe { GetTimeZoneInformation(&mut info) };
+    debug_assert!(result != 0xFFFFFFFF, "GetTimeZoneInformation failed");
     info
 }

Alternatively, if the callers can handle errors, consider returning a Result type.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
