PostgreSQL支持时区转换,可以使用AT TIME ZONE表达式或CONVERT_TIMEZONE函数。例如,将一个时间戳从UTC转换为PST(太平洋标准时间): sql SELECT (NOW() AT TIME ZONE 'UTC') AT TIME ZONE 'PST' AS utc_to_pst; 或者使用CONVERT_TIMEZONE函数: sql SELECT CONVERT
The AT TIME ZONE operator converts time stamp without time zone to/from time stamp with time zone, and time with time zone values to different time zones. Table 9.34 shows its variants. timestamp without time zone AT TIME ZONE zone → timestamp with time zone Converts given time stamp wi...
A time zone in PostgreSQL is a region that follows a specific set of rules for handling time. It allows us to store and display date and time values with a specific offset from UTC (Coordinated Universal Time). It allows us to accurately convert the date and time values to other time z...

postgresql---时间类型 postgresql⽀持的时间类型如下图所⽰：⽇期 date:建议⽇期的输⼊格式为1997-01-01，虽然也⽀持19970101,1/1/1997,Jan-1-1997等多种格式。时间戳 timestamp[(p)] with(without) time zone:其实配置⽂件是可以设置时区的，且做上层业务时也不会在多个时区间切换，所以⼀般...
PSQLException: Cannot convert the column of type TIMESTAMPTZ to requested type java.time.LocalDateTime.如果Postgres表的字段类型是TIMESTAMPTZ ，但是java对象的字段类型是LocalDateTime， 这时会无法转换映射上。Postgres表字段类型应该用timestamp 或者 java字段类型用Date。2.参数值不能用双引号 错误例子：WHERE ...
The timestamptz data type is a time zone-aware date and time data type. Internally, PostgreSQL stores the timestamptz in UTC value. When you insert a value into a timestamptz column, PostgreSQL converts the timestamptz value into a UTC value and stores the UTC value in the table. ...
