My source is a Kafka topic. I am using Event Time. I assign the event time with an AscendingTimestampExtractor
I noticed when debugging that in the KeyedProcessFunction that after my highest known event time of: 2020-06-23T00:46:30.000Z the processElement method had a watermark with an impossible date of: -292275055-05-16T16:47:04.192Z but in the onTimer method it had a more reasonable value that trails the highest known event time by 1 millisecond, which is this value: 2020-06-23T00:46:29.999Z I want to know, why does the processElement method have an impossible watermark value?
