configuration files that can be altered by a DBA. The australian_timezones GUC setting disappears, replaced by a timezone_abbreviations setting (set this to 'Australia' to get the effect of australian_timezones). The list of zone names defined by default has undergone a bit of cleanup, too. Documentation still needs some work --- in particular, should we fix Table B-4, or just get rid of it? Joachim Wieland, with some editorializing by moi.

This is a PostgreSQL adapted version of the timezone library
|
|
from:

|
|
|
ftp://elsie.nci.nih.gov/pub/tzcode*.tar.gz

The data files under data/ are an exact copy of the latest data set
|
|
from
|
|
|
|
ftp://elsie.nci.nih.gov/pub/tzdata*.tar.gz
|
|
|
|
Since time zone rules change frequently in some parts of the world,
|
|
we should endeavor to update the data files before each PostgreSQL
|
|
release.
|
|
|
|
At each update, we should check if time zone offsets have changed.
|
|
Just search for the current or previous year and see what has changed.
|
|
Sometimes a country changes its time zone offsets, for example Georgia
|
|
in 2004. Just grepping in the zic database files for 2004 is enough to
|
|
spot such a change. Then the files under tznames/ should be updated.
