There are some comments on time namespace at
<https://issues.guix.gnu.org/44559#3>.  Unfortunately, it only accepts
offsets in a limited range, so you can't just reset the clock to 1970.

There was also some talk on avoiding the no-CLOCK_REALTIME problem at
<https://logs.guix.gnu.org/guix/2022-06-08.log> with syscall rewriting.

Greetings,
Maxime.
