Laird, no, when a pom references a dependency, only the GAV attributes are used. This is Maven, when resolving this GAV against the remote repository that may use the time information to retrieve the last one. It is possible that your Nexus is configured so that only the n last items of an artifact are kept in the snapshot repo. This is done through Nexus tasks so check it.
