We can see the server’s timezone by using the show timezone command. The example below shows how to see the server timezone in PostgreSQL as follows. showtime zone; Output: In the above example, the current timestamp with the timezone is Asia/Kolkata; we can change the same by using...
SHOW TIMEZONE; 设置为中国的时区: SET TIMEZONE TO 'Asia/Shanghai'; 2. 配置字段 migrations设置如下: defchangedocreate table(:people)doadd:first_name,:string,size:100add:last_name,:string,size:100add:age,:integer,default:0add:create_time,:timestamptz,default:fragment("now()")endend ...
As documented in the manual必须是：
TIMESTAMP [(p)][WITHOUT TIMEZONE] CHAR(n),CHARACTER(n),VARCHAR(n),CHARACTER ,VARYING(n),TEXT STRING BYTEA BYTES 写入 内部类型 PostgreSQL 类型 TINYINT - SMALLINT SMALLINT,INT2,SMALLSERIAL,SERIAL2 INT INTEGER,SERIAL BIGINT BIGINT,BIGSERIAL ...
//我们只可以从一个 timestamp with time zone 的数据类型中截取TIMEZONE_HOUR和TIMEZONE_MINUTE; select extract(year from date'2011-05-17') year from dual; select extract(month from date'2011-05-17') month from dual; select extract(day from date'2011-05-17') day from dual; ...
I’ll assume that you follow my advice, given in Part One, to represent the moments at which the events happen always as timestamptz values. Arithmetic that uses clock time interval values and timestamptz values is independent of the session timezone. However, when, for example, you view ...
Time zone: Asia/Shanghai (CST, +0800) 但CST是一个多重含义的时区缩写,可表示以下时区: 美国中部时间:Central Standard Time (USA) UT-6:00 澳大利亚中部时间:Central Standard Time (Australia) UT+9:30 中国标准时间:China Standard Time UT+8:00 ...
