Modification date of /gnu/store files is 1970-01-01

[Martin Michel]

Hi,

I have install Guix on a Virtualbox VM in order to test if Guix could become my 
future GNU/Linux distribution of choice.  The installation went smoothly and I 
am learning the differences to Debian, my previous companion for many years, 
step-by-step.

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.

Can anyone help here?
