Then something peculiar to the Ubuntu groff seems to be behind this.
Ubuntu is a Debian-derived distro, and the concurrent "local timezone"
thread here points out Debian's proclivity to customize groff in
incompatible ways.

I don't have access to a Debian or Ubuntu system, but perhaps one of
our other troubleshooters here does and can look into it.  Or if you
can get ahold of a non-Debian-flavored groff, maybe see if that gives
you different results?  If you're willing to go through the trouble,
it might be instructive to build groff yourself from its source --
that way your OS, shell, environment, etc., will all be identical, and
only the groff executable will be different.
