the file looks correct at 1hr ahead of gmt (and 2hrs ahead for dst).
time timezone data is copied to the environment for use.  so
you will have to cp /adm/timezone/local /env/timezone or reboot
to get the effect.

reboot.

no.  you can cpu as another user, but you have a terminal, not a cpu server.
you can't cpu to a terminal.

there are many things about a standalone environment that aren't
ideal.  you're noticing some of them.  in a full plan 9 environment,
the idea is that a terminal doesn't have anything special on it.
if you boot it, it's your machine.  the files are on the fileserver which
would protect stuff like /adm/timezone/local from being changed.
and the authentication would be taken care of by the auth server.

the cpu command.  you need a cpu server for that.
