## 53.34. 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 53.34. 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
