1.7.8 Shared timestamp attributes

The timestamp attributes enable Suppliers to define when information in an IVES document was created or updated. The values are not intended for display by a Consumer, but rather as suggestions as to the caching and updating of the information by the Consumer.

The values should represent the state of the information in the element and all of the immediate children of the element. They are therefore only set on top-level elements that are contained directly within an <IvesMessage>. If a timestamped element contains a reference to another shared object (eg an <Event> containing a <DescriptionReference> to a shared <DescriptionDefinition>) and the shared element is updated then only the timestamp on the shared element would need to be updated, not the timestamp on all the elements that contain references to it.

Shared Attributes

creationTime

The creationTime is an optional timestamp as to the first time that a Supplier produced information about the containing element. This doesn't have to be the point at which they first told anyone about it, but rather the point at which they first became aware and started storing information internally about the element.

lastUpdateTime

The lastUpdateTime is an optional timestamp which is the point when any information within the element or its children changed state.
