Hi, PROCESSING_TIME or EVENT_TIME timer reports in first trigger of timer function in : OnTimerContext context.timestamp()=-290308-12-21T19:59:05.225Z
PROCESSING_TIME has known unresolved issue [1], but I didn’t expect that EVENT_TIME would report in @onTimer function weird timestamp in first trigger Failing example test [2]. It also happened to me with KafkaIO and FIleIO on FlinkRunner. I noticed that in tests there is set .advanceWatermarkTo(Instant.EPOCH) before you add elements why is that? I am not sure what is the correct behavior and what I am doing wrong. Thanks for advice [1] https://lists.apache.org/thread.html/46fbe4812624e6fec720e776bfe341b 400982472a8b7b3142d846704%40%3Cdev.beam.apache.org%3E [2] https://github.com/seznam/beam/commit/f2175dda43e69d189651b3d519ee 5327144bcdd3
