getEndTimeMillis()
Returns the end time if finished, the current time if running, or an undefined value if never started.
|
long |
getStartTimeMillis()
This will return the start time or an undefined value if never started.

getTimeIntervalMillis()
If state is
StatisticState.ACTIVE or StatisticState.FINISHED should always return getEndTimeMillis()-getStartTimeMillis . |

Creates a snapshot of this timer.
