Daily/hourly TumblingEventTimeWindows

Hi everyone,

is there an easy way to implement a tumbling event time window that tumbles at a certain time? Examples could be daily or hourly (tumbling at exactly 00:00, 01:00, 02:00 etc.) windows.

So in particular, for a daily window, the first window would be shorter than the rest, tumble at midnight and after that it would basically be the same as a regular 24h TumbilngEventTimeWindow.

Cheers,
Max

I have just noticed that this is exactly what it currently does. Reading the docs I assumed all windows would be of the same size.
