TIMESTAMPWITHTIMEZONEis a variant ofTIMESTAMPthat includes atime zone region name or atime zone offset in its value. The time zone offset is the difference (in hours and minutes) between local time and UTC (Coordinated Universal Time—formerly Greenwich Mean Time). This data type is useful ...
在这样的情况下,就可以选择Timestamp类型的一个拓展类型,timestamp with time zone。这样就可以把当前对应的时区信息加入到数据列中。 函数systimestamp返回标准类型就是timestamp with time zone。与一般timestamp类型不同的是,timestamp with time zone额外加入了当前时区的信息。 SQL> select systimestamp from dua...
If you store a TIMESTAMP value, and then change the time zone and retrieve the value, the retrieved value is different from the value you stored. This occurs because the same time zone was not used for conversion in both directions. The current time zone is available as...
In order to understand how the timestamp conversions work we first need to know what’s meant bycurrent time zone. 要了解时间戳转换的工作原理,我们首先需要了解当前时区的含义。 In short,current time zoneis the value of the SESSION time_zone. By default this is the SYSTEM time of the server...
MySQL 会将 TIMESTAMP 值从当前时区转换到 UTC 以进行存储,并在检索时从 UTC 转换回当前时区。 (This does not occur for other types such as DATETIME.) By default, the current time zone for each connection is the server’s time. (默认情况下,每个连接的当前时区是服务器时间。
MySQL converts TIMESTAMP values from the current time zone to UTC for storage, and back from UTC to the current time zone for retrieval. MySQL 会将 TIMESTAMP 值从当前时区转换到 UTC 以进行存储,并在检索时从 UTC 转换回当前时区。 (This does not occur for other types such as DATETIME.) By...
时区可根据每个连接进行设置。只要时区设置保持不变,检索到的值与存储的值相同。若存储 TIMESTAMP 值后更改时区并检索该值,检索到的值与存储的值不同,因为两个方向的转换没有使用相同的时区。当前时区可通过 time_zone 系统变量的值获得。详细信息可查阅 MySQL 服务器时区支持的文档。实际应用示例:...
For the issue cause, now the pipeline connector converts TIMESTAMP to TIMESTAMP_LTZ in MySqlTypeUtils.java#L194, while the original mysql source connector does not deal with TIMESTAMP WITH TIME ZONE, so it I think should only occur in e2e case. 👍 1 Contributor Jiabao-Sun commented Jan...
