public class DurationBetween
extends BinaryExpression
implements org.jvnet.jaxb2_commons.lang.Equals2, org.jvnet.jaxb2_commons.lang.HashCode2, org.jvnet.jaxb2_commons.lang.ToString2

The DurationBetween operator returns the number of whole calendar periods for the specified precision between the first and second arguments. If the first argument is after the second argument, the result is negative. The result of this operation is always an integer; any fractional periods are dropped. For Date values, precision must be one of Year, Month, Week, or Day. For Time values, precision must be one of Hour, Minute, Second, or Millisecond. For calculations involving weeks, the duration of a week is equivalent to 7 days. When calculating duration between DateTime values with different timezone offsets, implementations should normalize to the timezone offset of the evaluation request timestamp, but only when the comparison precision is hours, minutes, seconds, or milliseconds. If either argument is null, the result is null. Note that this operator can be implemented using Uncertainty as described in the CQL specification, Chapter 5, Precision-Based Timing.
