The root file system for an omicron1-brand zone begins with the contents of the baseline archive. This archive is constructed either at startup on a developer workstation, or at ramdisk image build time for production machines. In both cases, we ship stock files from the original OS packages, including for the /etc/default/init. This file defines the system timezone, which is set by default to Pacific time for historical reasons:

$ cd /tmp

$ tar xvfz /usr/lib/brand/omicron1/baseline/files.tar.gz root/etc/default/init
Decompressing '/usr/lib/brand/omicron1/baseline/files.tar.gz' with '/usr/bin/gzcat'...
x root/etc/default/init, 1235 bytes, 3 tape blocks

$ cat root/etc/default/init

As part of baseline construction, we should replace the contents of this file with one that specifies TZ=UTC so that all zones operate with our expected timezone.

While I know there's a ton of stuff going on right now, I'm hopeful this is an easy fix that we can get into FCS?
