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.
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.
Table 45-61. pg_timezone_names Columns
| Name | Type | Description |
|---|---|---|
| name | text | Time zone name |
| abbrev | text | Time zone abbreviation |
| utc_offset | interval | Offset from UTC (positive means east of Greenwich) |
| is_dst | boolean | True if currently observing daylight savings |
