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 does not use 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
||Time zone name|
||Time zone abbreviation|
||Offset from UTC (positive means east of Greenwich)|
||True if currently observing daylight savings|
