Bizarre, never noticed that before -- there is no such anomoly with
the UNIX based server (npfs anyways).   Looking at the stat(5) man
page, looks like 9p is supposed to deliver mtime and atime in terms of
GMT. It would then be the responsibility of the client to adjust for
his/her local time zone.  I don't believe we are doing that at the
moment.  I'll add it to the bug list.  Thanks.
