The most likely reason to see this message (and have a wrong system
date) is that your hardware clock is wrong.  This shouldn't be an issue
anymore on recent Guix, but older Guix NTP service configuration used to
refuse to update your clock if there was a discrepancy of more than 3600
s between your hardware clock and the system clock (the one sync'd with
the NTP server).

So, either:

1. Update your hardware clock
2. Use a recent Guix, and let some time for the NTP service to sync your
clock.

As an alternative to 2, you could set the "allow-large-adjustment?"
field of your NTP configuration to #t manually (that's what Guix does by
default since commit 08b4a10fa6b).

HTH!
