1. timestamp和timestamptz类型的数据虽然都不保存时区信息,但是timestamptz却通过结合数据库设置的时区,session对应的时区以及timestamptz本身保存的数据,将正确的时间返回给客户端。也就是说从宏观上,timestamptz看起来确实像是保存了时区信息的timestamp数据,只不过这个时区是整个数据库设置
We can use the NOW and CURRENT_TIMESTAMP functions to get the current date and time in PostgreSQL, similar to MySQL. However, we also get the time zone in the result. To eliminate the time zone, we can run: -- using NOW function SELECT NOW()::TIMESTAMP; -- using CURRENT_TIMESTAMP...
which seems to imply there is a conversion by the jdbc driver to UTC, meaning it is altering the data as returned by the server. However, following the advice above, adding my timezone to the VM Options for the PostgreSql Driver fixed the issue. (Adding it to datagrip64.exe.vmoptions ...

比如,我们可以自定义一些 Event 类型(包含了 user、url 和 timestamp 三个字段,参考 5.2.1 小节中的定义)的用户访问事件,作为输入的数据源;而后从中提取 url 地址和用户名 user 两个字段作为输出。如果使用 DataStream API,我们可以直接读取数据源后,用一个简单转换算子 map 来做字段的提取。而这个需求直接写 ...
