The getCreationTime returns a PersonTime object ... it is for owners to set/get the time it took to create that asset. In any case this API was deprecated, as it was not really used.
What you are looking is for the activities of that Asset... specifically when was it submited (activity 675) or when it was created from an older version (new version, activity 685).
public static void main(String[] args) {
RAMSession session = new RAMSession("http://localhost:8080/ram.ws", "admin", "admin");
session.setWebServiceTimeout(10000);
RAMAsset asset = session.getAsset(new AssetIdentification("{0C972087-F35B-2907-8505-8A8EA00EF600}", "1.0"));
Calendar cal = Calendar.getInstance();
cal.setTime(new Date());
long now = cal.getTimeInMillis();
try {
RAMAssetActivity[] activities = asset.getActivites(new int[] {675,685}, 0, now );
for (RAMAssetActivity ramAssetActivity : activities) {
cal.setTimeInMillis(ramAssetActivity.getTimestamp());
System.out.println(cal.getTime());
}
} catch (EntitlementException e) {
e.printStackTrace();
} catch (AssetNotFoundException e) {
e.printStackTrace();
} catch (RAMException e) {
e.printStackTrace();
}
// upload/create the new version to the repository
// Make sure to create the asset with its artifacts, before removing things off
session.put(asset, new NullProgressMonitor());
session.release();
}
