 - 插入记录时，如果时间戳为0，插入数据时使用服务器当前时间
 - Epoch Time: 时间戳也可以是一个长整数，表示从1970-01-01 08:00:00.000开始的毫秒数
 - 时间可以加减，比如 now-2h，表明查询时刻向前推2个小时(最近2小时)。数字后面的时间单位：a(毫秒), s(秒), m(分), h(小时), d(天)，w(周), n(月), y(年)。比如select * from t1 where ts > now-2w and ts <= now-1w, 表示查询两周前整整一周的数据
+- TDengine暂不支持时间窗口按照自然年和自然月切分。Where条件中的时间窗口单位的换算关系如下：interval(1y) 等效于 interval(365d), interval(1n) 等效于 interval(30d), interval(1w) 等效于 interval(7d)
 
 TDengine缺省的时间戳是毫秒精度，但通过修改配置参数enableMicrosecond就可支持微秒。
