是一个 timestamp without time zone,而 TIMESTAMP '2021-03-06 18:02:00 +08' 1. 是一个 timestamp with time zone。 +08:表示 时区与全球统一时间 UTC 偏移量为 8 小时 AT TIME ZONE 构造允许把时间戳转换成不同的时区与timezone(zone,timestamp) 函数等效 SELECT current_timestamp AT TIME ZONE '...
test=# select current_timestamp(0)::timestamp without time zone; timestamp --- 2016-01-11 17:43:50 (1 row) 4、使用cast函数做类型转换去掉时区 test=# select cast(current_timestamp(0) as timestamp without time zone); timestamp --- 2016-01-11 17:44:10 (1 row) 三、标准格式 1)日...
The PostgreSQL “TIMESTAMP” or “TIMESTAMP WITHOUT TIME ZONE” data type stores a timestamp value without the time zone information. In Postgres, the TIMESTAMP and TIMESTAMPTZ data types are similar; the only difference is that one includes the time zone information while the other doesn’t....

In PostgreSQL, If you only want the current date-time by calling CURRENT_TIMESTAMP() without time zone, and fractional digits in the seconds field which come after the decimal point of the seconds field? (Tested on PostgreSQL v12.4) Then use this: SELECT CURRENT_TIMESTAMP(0)::TIMESTAM...
PostgreSQL提供了大量用于获取系统当前日期和时间的函数,例如current_date、current_time、current_timestamp、clock_timestamp()、localtimestamp、now()、statement_timestamp()等;同时还支持延迟语句执行的pg_sleep()等函数 时区转换 AT TIME ZONE运算符用于将timestamp without time zone、timestamp WITH time zone以...
I want to insert the current time in GMT in this column. When getting the current time and inserting it into the DB it's inserted in the server timezone GMT-5 although that time was in GMT+0. Any ideas how to insert this time in the database in GMT timezone?
First, as explained above, timestamp without time zone AT TIME ZONE re-interprets the timestamp as being in that time zone for conversion to a UTC timestamptz; this effectively subtracts the timezone offset. However, for reasons I beyond my ken, PostgreSQL uses timest...
Cause: org.postgresql.util.PSQLException: ERROR: function date_format(timestamp without time zone, unknown) does not exist PostgreSQL没有date_format函数，用to_char函数替换。替换例子：// %Y => YYYY // %m => MM // %d => DD // %H => HH24 // %i => MI // %s => SS to_char(time...
