Sometimes search indexing and build tools get it wrong, so if you know what you're doing, then tools like this allow you to provide an override.

Just browsing an old photo collection without making any changes can cause a 15 year old file to show up as a "new file", even though it's contents have not changed. This is especially true with media files that the os might take it upon itself to regenerate metadata for.

Or you may wish to store an accurate snapshot of the timestamps of cached or intermediate build artifacts.
