                    var HALF_HOUR_OFFSET = 1800000;

                    var extractedDate = lastValue.substring(0,10); //parsing the date of the last saved date

                    db.DB_COLLECTION.find({ COLLECTION_FIELD: { $gte : bottomEpoch, $lte: upperEpoch} },{'_id': false}); //we omit the 'id' since it irrelevant and also cause deserialize exception
