 - 查询过滤、聚合等操作按照每个切分窗口为独立的单位执行。聚合查询目前支持三种窗口的划分方式：
   1. 时间窗口：聚合时间段的窗口宽度由关键词 INTERVAL 指定，最短时间间隔 10 毫秒（10a）；并且支持偏移 offset（偏移必须小于间隔），也即时间窗口划分与“UTC 时刻 0”相比的偏移量。SLIDING 语句用于指定聚合时间段的前向增量，也即每次窗口向前滑动的时长。当 SLIDING 与 INTERVAL 取值相等的时候，滑动窗口即为翻转窗口。
     * 从 2.1.5.0 版本开始，INTERVAL 语句允许的最短时间间隔调整为 1 微秒（1u），当然如果所查询的 DATABASE 的时间精度设置为毫秒级，那么允许的最短时间间隔为 1 毫秒（1a）。
-  2. 状态窗口：使用整数（布尔值）或字符串来标识产生记录时设备的状态量，产生的记录如果具有相同的状态量取值则归属于同一个状态窗口，数值改变后该窗口关闭。状态量所对应的列作为 STATE_WINDOW 语句的参数来指定。
+    * **注意：**用到 INTERVAL 语句时，除非极特殊的情况，都要求把客户端和服务端的 taos.cfg 配置文件中的 timezone 参数配置为相同的取值，以避免时间处理函数频繁进行跨时区转换而导致的严重性能影响。
