+public class OrderedTimeRange
Review comment:
TBH, the main value add here is more readable restriction bounds /
values in the error messages for the context of the time range use case.
If there is a cleaner way of borrowing all implementation from
OffsetRangeTracker but changing format of these error messages, I'd be all ears.
I suppose I could add a `private final bool offestsAreInstants` member to
OffsetRangeTracker and throw conditional formatting on each error message?

> Key: BEAM-9856
> URL: https://issues.apache.org/jira/browse/BEAM-9856
> Project: Beam
> Issue Type: Improvement
> Components: io-java-gcp
> Reporter: Jacob Ferriero
> Assignee: Jacob Ferriero
> Priority: Minor
> Time Spent: 2h 50m
> Remaining Estimate: 0h
>
> Currently the List Messages API paginates through in a single ProcessElement
> Call.
> However we could get a restriction based on createTime using Messages.List
> filter and orderby.
>
> This is inline with the future roadmap of HL7v2 bulk export API becomes
> available that should allow splitting on (e.g. create time dimension).
> Leveraging this bulk export might be a future optimization to explore.
>
> This could take one of two forms:
> 1. dyanmically splitable via splitable DoFn (sexy, beam idiomatic: make
> optimization the runner's problem, potentially unnecessarily complex for this
> use case )
> 2. static splitting on some time partition e.g. finding the earliest
> createTime and emitting a PCollection of 1 hour partitions and paginating
> through each hour of data w/ in the time frame that the store spans, in a
> separate ProcessElement. (easy to implement but will likely have hot keys /
> stragglers based on "busy hours")
