: when I've checked the new data, I see datetime value have one hour less than : current date.
Please note the documentation about DateField (and TrieDateField which extends it)... https://lucene.apache.org/solr/4_1_0/solr-core/org/apache/solr/schema/DateField.html The response format is *always* in UTC so that it is consistent for all clients, regardless of what locale the server is running in -- because the clients may not *know* what locale the server is running in. If you use SolrJ then you will get java.util.Date objects back and you can format them in whatever local your client would like. Note however that clients can specify a "TZ" param when making requests to control the timezone used for the purposes of *rounding* -- eg: if you say "NOW/DAY" the TZ specified will determine when the start of the day is, but the resulting Date value will still be formated in UTC so it can consistently be interpreted in all clients. (Aparently the "TZ" param has never really been documented ... i'll try to rectify that) -Hoss
