Description
When working on a custom Processor from which I am scheduling a punctuation using WALL_CLOCK_TIME. I've noticed that whatever the punctuation interval I set, a call to my Punctuator is always triggered immediately.
Having a quick look at kafka-streams' code, I could find that all PunctuationSchedule's timestamps are matched against the current time in order to decide whether or not to trigger the punctuator (org.apache.kafka.streams.processor.internals.PunctuationQueue#mayPunctuate). However, I've only seen code that initializes PunctuationSchedule's timestamp to 0, which I guess is what is causing an immediate punctuation.
At least when using WALL_CLOCK_TIME, shouldn't the PunctuationSchedule's timestamp be initialized to current time + interval?
