While that does work (on my intrepid systems), it creates the problem of
having to change the file each time you move from one timezone to
another (think laptop + travel). So in order to use it as a reasonable
workaround, I think you'd need to figure out how to have the file be
automatically updated from /etc/timezone. Otherwise your stuck on left
coast time forever.

Further, I think that it's important to figure out why the issue doesn't
occur on hardy, but does occur on intrepid. Both hardy systems that I
tested are upgrades from d-e-f-g-hardy. I've another system that has a
fresh hardy install on it that I can test tomorrow to see if it occurs
on that system as well.
