The view
pg_timezone_names
provides a list
of time zone names that are recognized by
SET TIMEZONE
,
along with their associated abbreviations, UTC offsets,
and daylight-savings status. (Technically,
PostgreSQL
uses
UT1
rather
than UTC because leap seconds are not handled.)
Unlike the abbreviations shown in
pg_timezone_abbrevs
, many of these names imply a set of daylight-savings transition
date rules. Therefore, the associated information changes across local DST
boundaries. The displayed information is computed based on the current
value of
CURRENT_TIMESTAMP
.
