All Implemented Interfaces:
java.io.Serializable, Statistic, com.ibm.websphere.management.statistics.Statistic, com.ibm.websphere.management.statistics.TimeStatistic
public class TimeStatisticImpl
extends StatisticImpl
implements com.ibm.websphere.management.statistics.TimeStatistic

TimeStatisticImpl: implements JSR77's TimeStatistic and extends StatisticImpl.

Note: PMI provides more performance data than JSR77 specification. A TimeStatistic data in PMI may keep tracking a non-time related metric. For example, the data tracking the average read/write size in session manager is of TimeStatistic type but not a time-related metric. PMI does not invent a new data type since TimeStatistic perfectly match the requirement except that the name itself might be misleading. However, the unit for the data should clarify any confusion.
