public class MomentType

extends TimestampType

Moment is like a timestamp but when it is added to or subtracted from any other time/date value, the result will be the given moment.

Format syntax

Moment type inherits it's formatting functionality from it's DateFormatType superclass.

Since:

JDK1.1
