You can do this very easily in CVS tip. I assume you want something like
this:
alvherre=# show timezone; TimeZone
------------------America/Santiago
(1 fila)
alvherre=# select '00:00:00 GMT'::timetz at time zone 'Chile/EasterIsland'; timezone
-------------18:00:00-06
(1 fila)
alvherre=# select '00:00:00 GMT'::timetz at time zone 'Chile/Continental'; timezone
-------------20:00:00-04
(1 fila)
Not sure if that helps you any. I think you could build a table using
this and the fact that "postmaster -d3" prints the whole table of known
timezones. (You could extract that bit from the zic files as well.)
