- Method Detail
  - getTimestamp
```
Instant getTimestamp()
```
    Temporal state describing the time at which this item was last updated. Relates to the Temporal interface and is primarily used during consumption of messages regarding changes in state to this domain. For example, a service consuming a change notification for this domain can compare the current persisted timestamp to this timestamp to determine if it already has a newer version, in which case, it can ignore. This is primarily a measure to ensure that ordering is not required for messages related to state change.
    
    Returns:
    
    Temporal state describing the time at which this item was last updated
  - setTimestamp
```
