timezone offsets and documentation

The documentation says the time with time zone datatype allows zone
offsets from +12 to -12.

http://www.postgresql.org/docs/8.0/static/datatype-datetime.html

This is at odds with the implementation which allows values +1359 to -1359

jurka=# select '00:00:00+1359'::timetz;
timetz
----------------
00:00:00+13:59
(1 row)

Further the list of available timezone names says that Etc/GMT-14 is a
valid timezone.

http://www.postgresql.org/docs/8.0/static/datetime-keywords.html#DATETIME-TIMEZONE-SET-TABLE

This allows:

jurka=# set timezone to 'Etc/GMT-14';
SET
jurka=# select '00:00:00'::timetz;
timetz
-------------
00:00:00+14
(1 row)

but this is not an allowed value:

jurka=# select '00:00:00+14'::timetz;
ERROR: time zone displacement out of range: "00:00:00+14"
