Hi All, I saw that in the Python SDK we encode WindowedValues <https://github.com/apache/beam/blob/b4f02888aed20f6f066d07f4ff26e6688a6f848e/sdks/python/apache_beam/coders/coder_impl.py#L1082> and Timestamps <https://github.com/apache/beam/blob/b4f02888aed20f6f066d07f4ff26e6688a6f848e/sdks/python/apache_beam/coders/coder_impl.py#L598> as millis, whereas the TIME_GRANULARITY <https://github.com/apache/beam/blob/master/sdks/python/apache_beam/utils/timestamp.py#L418> is defined as 1us. Why do we do this? Won't this cause problems using the FnApiRunner as windows might fire out of order or something else?
Thanks, Sam
