So far so good, but I could not figure out what is wrong with the file system entries of /gnu/store. All entries there have a timestamp of UNIX epoch 0.

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,
