stack commented on HBASE-6833:
------------------------------
This one is a bit of a bummer. As you suggest elsewhere, in tests, could user
EnvironmentEdge thing that updates each time its called but what happens when
you run in production? You are going to get odd results.
This does bring to the fore how much we presume a forward moving clock (Those
spanner time servers with their aerials for GPS and atomic clock cards start to
make a bit more sense now)

> Key: HBASE-6833
> URL: https://issues.apache.org/jira/browse/HBASE-6833
> Project: HBase
> Issue Type: Sub-task
> Affects Versions: 0.96.0, 0.94.3
> Reporter: Enis Soztutar
> Assignee: Enis Soztutar
> Labels: windows
>
> HBase relies on the system clock obtained by System.currentTimeMilis() to
> supply the version, if it is not provided by the client in Put's and
> Delete's. At HBASE-6832 and HBASE-6826, we discovered that on some platforms,
> the milis clock might not be updated every milisecond, which might cause
> unexpected behavior. We also did some preliminary analysis there.
> In this issue, we can further discuss and inspect whether it is a problem for
> main target platforms and if so what can be done.
