Direct Known Subclasses:

EventInSFTimeWrapper

public abstract class EventInSFTime
extends EventIn

VRML eventIn class for SFTime.

Time values are represented as per the VRML IS specification Section 4.11 Time. That is, time is set as VRML "Time" - the number of seconds since Jan 1, 1970 GMT, rather than a Java time which is a long, the number of milliseconds since Jan 1, 1970 GMT. To convert between the two simply divide java time by 1000 and cast to a double.

Note that in setting time values from an external application, the idea of the time that java represents and the time that the VRML world currently has set may well be different. It is best to source the current "time" from a node or eventOut in the VRML world rather than relying exclusively on the value returned from System.currentTimeMillies. This is especially important to note if you are dealing with high speed, narrow interval work such as controlling animation.
