I mean that where the tzcode uses "GMT" as a default zone name or
abbreviation in the absence of data, FreeBSD uses "UTC" (and has since

e.g. with no /etc/localtime file,

% env -u TZ date
Tue  5 May 2020 00:00:37 UTC

(To the best of my knowledge there are no reference clocks available to
which one could synchronize in order to use a mean solar time, so your
argument seems to me to support this choice.)
