Subject: [PATCH 1/4] services: ntp: Allow large adjustment by default.
This is documented as best practice in `man ntpd', and is required to allow
the date to be set correctly when traveling (without having to manually update
the hardware clock in the BIOS/UEFI).
* gnu/services/networking.scm ()[allow-large-adjustment?]: Set the
default value to #t.
* doc/guix.texi (Networking Services): Update documentation.
