getScheduledDeletionDate always returns 0

[shafr]

When using browser or checking source code for json for specific project, I can see the getScheduledDeletionDate(), like below

When using java api the result value is always 0:

ProjectView projectByName = projectService.getProjectByName("<my project>").get();

List<ProjectVersionView> allProjectVersions = projectService.getAllProjectVersions(projectByName);
for (ProjectVersionView rallyProject : allProjectVersions) {
    rallyProject.getScheduledDeletionDate() // Always 0
}
