    Thanks for the review, @fhueske. I tried to consolidate the logics for proctime and rowtime
watermark processing, but failed. That's because when using proctime, the "watermark" (not
sure if this concept exists for proctime) for triggering the timers is set to be identical
with the current record's processing time, thus all the records will be considered late. Do
you think it's necessary to unify their behaviors, or we just take the proctime as a special
case?
