You only need one tool that doesn't quite do things right to lose that:
- file copy programs need to explicitly set the creation date back to that of the original file.
- when you do save a file in an editor, it typically writes a complete new file (ideally through a write temp file/delete/rename dance). Again, the program may forget to reset the creation date of the new file to that of the original.
- I don't think got even _stores_ creation time stamps in repositories.
I've seen too many files with obviously bogus creation time stamps to put much trust in the creation dates of files.
