SolrCloud has had that behavior from day one, when it was released in version 4.0. You are correct that it can result in a different timestamp on each replica if the default comes from schema.xml. I am pretty sure that the solution for this problem is to set up an update processor chain that includes TimestampUpdateProcessorFactory to populate the timestamp field before the document is distributed to each replica. https://cwiki.apache.org/confluence/display/solr/Update+Request+Processors Thanks, Shawn
