包路径：com.zsmartsystems.zigbee.zcl.ZclAttribute
类名称：ZclAttribute
方法名：isLastValueCurrent

ZclAttribute.isLastValueCurrent介绍

[英]Checks if the last value received for the attribute is still current. If the last update time is more recent than the allowedAge then this will return true. allowedAge is defined in milliseconds.
[中]检查为属性接收的最后一个值是否仍然是当前值。如果上一次更新时间比允许的时间更晚，则返回true。allowedAge是以毫秒为单位定义的。
