Hi,
这可能是个Bug。 Blink中默认使用timestamp WITHOUT time zone,所以它是无时区的。 而proctime目前还是带时区的产生了时间,我理解可能是应该产生无时区的时间。 CC: @Jark Wu <[hidden email]> @Zhenghua Gao <[hidden email]> Best, Jingsong Lee On Tue, May 5, 2020 at 5:43 PM 祝尚 <[hidden email]> wrote: > 同问,等待大佬回答 > > > 2020年5月1日 下午5:26,hb <[hidden email]> 写道: > > > > > > > > ``` 代码 > > val env = StreamExecutionEnvironment.getExecutionEnvironment > > val settings: EnvironmentSettings = > EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build() > > val tEnv: StreamTableEnvironment = StreamTableEnvironment.create(env, > settings) > > > > > > val t2 = env.fromElements("a", "b", "c") > > t2.toTable(tEnv, 'f1, 'proc.proctime).toAppendStream[Row].print() > > ``` > > > > > > // 时区上海, 当前时间为 2020-05-01 15点 > > // 结果显示 a,2020-05-01T09:11:05.633, 处理时间相差8小时, 请问如何让 proctime 结果显示不差8小时. > > -- Best, Jingsong Lee |

Yes. This is the same problem with CURRENT_TIMESTAMP which was asked before
in mailing list and JIRA. Changing the return type to WITH LOCAL TIME ZONE is not a small work, we should make event-time and watermark support this type. But I think this is in a high priority and should be fixed in the next release.

Hi,
一种简单的方式,自己手动在proctime上加8个小时,目前这个时区设置好像是不起作用的。 > -----原始邮件----- > 发件人: hb <[hidden email]> > 发送时间: 2020-05-12 13:02:44 (星期二) > 收件人: [hidden email] > 抄送: > 主题: Re:flink sql 处理时间 时区问题 > > 有人能帮忙看下这个问题么 > > > > 在 2020-05-01 16:26:35,"hb" <[hidden email]> 写道: > > > > ``` 代码 > val env = StreamExecutionEnvironment.getExecutionEnvironment > val settings: EnvironmentSettings = EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build() > val tEnv: StreamTableEnvironment = StreamTableEnvironment.create(env, settings) > > > val t2 = env.fromElements("a", "b", "c") > t2.toTable(tEnv, 'f1, 'proc.proctime).toAppendStream[Row].print() > ``` > > > // 时区上海, 当前时间为 2020-05-01 15点 > // 结果显示 a,2020-05-01T09:11:05.633, 处理时间相差8小时, 请问如何让 proctime 结果显示不差8小时. > > > > > ------------------------------ 刘大龙 浙江大学 控制系 智能系统与控制研究所 工控新楼217 地址:浙江省杭州市浙大路38号浙江大学玉泉校区 Tel:18867547281 |
