-----------------------------------------------

I recently raised an issue HBASE-6784 again a testcase failure just because the 
Puts got the same timestamp and the test was failing randomly.
Based on the discussion over here i can provide a patch for that HBASe-6784.

> 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.
