Some doubts about window start time and end time

Hi:
I defined a Tumbling window, I set the time size to one hour, and the resulting windows are [00: 00: 00-01: 00: 00], [01: 00: 00-02: 00: 00]. ....
This meets my expectations, but when I set the time size to 6 hours, the resulting window size is [02: 00: 00-08: 00: 00], [08: 00: 00-14: 00: 00], [14: 00: 00-20: 00: 00] ...
But my expected window size is [00: 00: 00-06: 00: 00], [06: 00: 00-12: 00: 00] ...
Is it right to get such a window result?



thanks

Hi Jun,

How do you define your window? Could you please show us the code?
