I've fixed the minor issue here, which is that the sign is backwards ---
it ought to select "Etc/GMT+4". The larger issue is that it's not
recognizing your system timezone because the only name it can cons up
for the zone is "CLT4CLST", which doesn't work because it has the wrong
DST rules. (I think it's just luck that it realizes that, actually :-().
Magnus and I had talked off-list about a smarter routine to recognize
the system timezone without a TZ setting, but the only idea we've had is
to grovel through each and every timezone file in the zic database,
which doesn't seem real appealing.

Right, that much is fixed anyway.

Fixed.

Fixed.
