I debootstrap** Debian for those times I need a new installation.
These were the instructions I'd been using up until last time (maybe a
year ago):

https://www.debian.org/releases/stretch/amd64/apds03.html.en#idm4468

Basically that says;

=== BEGIN SNIPPET

# editor /etc/adjtime

Populate that with:

0.0 0 0.0

0
UTC

To configure timezone;

# dpkg-reconfigure tzdata

=== END SNIPPET

During debootstrap, the /etc/adjtime file doesn't exist until that
step is run, but it's also a brand new install that hasn't been booted
a first time yet.

That manually created file then works flawlessly for me here, but my
needs are simple. I think the hardware clock is set to UTC, by the
way.

** N.B. Debootstrap was priceless as a method of installing Linux on
dialup Internet connections.. in case that still helps anyone else.
