- Method Detail
  - update
```
void update(Duration duration)
```
    Adds a recorded duration.
    
    Parameters:
    
    duration - the length of the duration
  - time
```
<T> T time(Callable<T> event)
    throws Exception
```
    Times and records the duration of event.
    
    Type Parameters:
    
    T - the type of the value returned by event
    
    Parameters:
    
    event - a Callable whose Callable.call() method implements a process whose duration should be timed
    
    Returns:
    
    the value returned by event
    
    Throws:
    
    Exception - if event throws an Exception
  - time
```
void time(Runnable event)
```
    Times and records the duration of event.
    
    Parameters:
    
    event - a Runnable whose Runnable.run() method implements a process whose duration should be timed
  - time
```
Timer.Context time()
```
    Returns a new Timer.Context.
    
    Returns:
    
    a new Timer.Context
