Vikas Kedigehalli updated BEAM-1524:
------------------------------------
Description:
Runners cannot have a timestamp precision that is lesser than what a SDK uses.
Also with Fn API a runner should be able to support multiple SDKs that maybe
written in different languages. It is important that we standardize the
precision of timestamp to ensure that runners are compatible across all the
SDKs.
NOTE: Timestamps are shifted such that lexicographic ordering of the bytes
corresponds to chronological order. This also needs to be consistent across
SDKs.
