ExifTool Linux version can't extract "Date Time Original" and "File Creation Date/Time" embedded metadata values for BMP and GIF files but ExifTool windows i.e exiftool.exe can extract those values.
Can you please let us know why ExifTool windows extracts but Linux version can't.
Thanks

Funny. Someone else just asked this same question (https://exiftool.org/forum/index.php/topic,5284.0.html)
This applies for FileCreateDate. However, DateTimeOriginal is metadata in the file, so it will be extracted the same on all systems.
