   …ta type with precision 3
   
   Now the window_start and window_end has a type of a Timestamp with
   default system precision. But, actually, many DB vendors has default
   precision as 6 (which is also defined in the SQL standard).
   
   We better promote the precision to 3 because:
   1. For windowing, time unit as millisecond is enough
   2. Make the precision deterministic instead of overriding by each
   engine's default one
