> Key: BEAM-1524

> Project: Beam
> Issue Type: Improvement

> Reporter: Vikas Kedigehalli
> Priority: P3
> Labels: Clarified
>
> 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.
