> Goal is to provide a UDF that truncates a timestamp to a beginning of a
> tumbling window interval.

> * Tumbling windows are inclusive start exclusive end.
> * By default the beginning instant of fist window is Epoch 0 Thu Jan 01
> 00:00:00 1970 UTC.

> *
> * This an example of series of window with an interval of 5 seconds and
> origin Epoch 0 Thu Jan 01 00:00:00 1970 UTC:

> * interval 1 interval 2 interval 3
> * Jan 01 00:00:00 Jan 01 00:00:05 Jan 01 00:00:10
> * 0 -------------- 4 : 5 --------------- 9: 10 --------------- 14
