public class Now
extends OperatorExpression
implements org.jvnet.jaxb2_commons.lang.Equals2, org.jvnet.jaxb2_commons.lang.HashCode2, org.jvnet.jaxb2_commons.lang.ToString2

The Now operator returns the date and time of the start timestamp associated with the evaluation request. Now is defined in this way for two reasons: 1) The operation will always return the same value within any given evaluation, ensuring that the result of an expression containing Now will always return the same result. 2) The operation will return the timestamp associated with the evaluation request, allowing the evaluation to be performed with the same timezone offset information as the data delivered with the evaluation request.
