damccorm opened a new issue, #19922:
URL: https://github.com/apache/beam/issues/19922
The current proto representation of timesetamp and durations in Beam is
either raw int64s or the well-known Google protobuf types
"google.protobuf.timestamp" and "google.protobuf.duration". Apache Beam uses
int64 MAX and MIN as sentinel values for an ****inf watermark and -inf
watermark. However, the google.protobuf.timestamp is compliant with RFC3339,
meaning it can only represent date-times between 0001-01-01 and 9999-12-31.
This is not the same as the int64 MAX and MIN representation. The questions
remain:
* What should the timestamp and duration representations be?
* What units should the timestamps and duration be? Nanos? Micros?
* What algebra is allowed when dealing with timestamps and durations? What
is needed?
