Examples of org.apache.wicket.util.time.Time

org.apache.wicket.util.time.Time
An immutable Time class that represents a specific point in time. The underlying representation is a long value which holds a number of milliseconds since January 1, 1970, 0:00 GMT. To represent a duration of time, such as "6 seconds", use the Duration class. To represent a time period with a start and end time, use the TimeFrame class. To represent a time of day, use the TimeOfDay class. @author Jonathan Locke @since 1.2.6
