[GitHub] [beam] kennknowles opened a new issue, #18337: Improve error message for shifting elements back in time

kennknowles opened a new issue, #18337:
URL: https://github.com/apache/beam/issues/18337

   When an element is shifted forwards in time (often to the end of the Global Window) as a result of a GroupByKey, they can't be reassigned the timestamps the user expects. This is fine, but users don't understand why the elements have been shifted forwards, and we should improve the messaging around this error.
