> Currently, time-based group windows can be defined using intervals of milliseconds such as {{.window(Tumble over 10.minutes on 'rowtime as 'w)}}. For some use cases it might useful to define windows of months (esp. in event-time) that work even with leap years and other special time cases.
> The following should be supported in Table API & SQL:
> {{.window(Tumble over 1.month on 'rowtime as 'w)}}
