## 51.92. `pg_timezone_names`

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 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 `CURRENT_TIMESTAMP`.

Table 51.93. `pg_timezone_names` Columns

Column 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` `bool` True if currently observing daylight savings
