The Python SDK currently uses timestamps in microsecond resolution while Java SDK, as most would probably expect, uses milliseconds.
This causes a few difficulties with portability (Python coders need to convert to millis for WindowedValue and Timers, which is related to a bug I'm looking into: https://issues.apache.org/jira/browse/BEAM-7035 As Luke pointed out, the issue was previously discussed: https://issues.apache.org/jira/browse/BEAM-1524 I'm not privy to the reasons why we decided to go with micros in first place, but would it be too big of a change or impractical for other reasons to switch Python SDK to millis before it gets more users? Thanks, Thomas
