44.58. 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. 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 44-59. 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)
