I believe the TZ (and TZNAME) environment variables are set automatically in
the Unix environment, at least in US. It's the automatic setting feature that
really bugs us who live Arizona (we don't have summer saving time). What I
ended up doing (learn from suggestion in comp.sys.apollo long time ago) is to
add the TZ and TZNAME in /etc/rc and /sys/node_data/startup.* files so we
always have the right timezone setting.

Try setting TZ in /sys/node_data/startup.*, such as in our
/sys/node-data/startup.1280color file:

# to defeat automatic summer saving time
ENV TZ MST7
ENV TZNAME MST
