             Summary: System.currentTimeMillis usage in BookKeeper
                 Key: BOOKKEEPER-327
                 URL: https://issues.apache.org/jira/browse/BOOKKEEPER-327
             Project: Bookkeeper
          Issue Type: Bug
            Reporter: Rakesh R
            Priority: Minor


The following exception occured in the bookie statistics logic due to the 
System time changes. In our bookie cluster its running a periodic syncup 
scripts just to unify the SystemTime in all the machines. This is causing the 
problem and resulting ArrayIndexOutOfBoundException.
{code}
Exception in thread "BookieJournal-3181" 
java.lang.ArrayIndexOutOfBoundsException: -423
at org.apache.bookkeeper.proto.BKStats$OpStats.updateLatency(BKStats.java:126)
at org.apache.bookkeeper.proto.BookieServer.writeComplete(BookieServer.java:655)
at org.apache.bookkeeper.bookie.Journal.run(Journal.java:507)
{code}

This jira is raised to discuss whether to use ??System.nanoTime()?? instead of 
??System.currentTimeMillis()??
