+ * difference between the first query written by each command.
+ *
+ * - All N queries are timestamp values. If two timestamps are written
+ * in the same subpass, the sum of the execution time of all views
+ * between those commands is the sum of the difference between
+ * corresponding queries written by each command. The difference
+ * between corresponding queries may be the execution time of a
+ * single view.
