Well spotted! This is intentional. The Guix daemon[0] changes
all timestamps of all files added to the store to a known value.
Same for other metadata like ownership and some permission bits.
If it did not, certain software could (and does) behave
differently between two different machines with otherwise
identical stores.
Kind regards,
