我只是在寻找一些关于如何制定最佳会议时段的建议。因此，学生会议不会重叠，也不会太远。我正在尝试计算推荐的时间，以便父母可以看到最好的预订位置，以便他们不会等待。
例如它应该如何运作：
父母1：
Child 1 and Child 2
会议1：
Slot `2016-10-07 14:00:00` (free)(duration 10mins)(Child 1)
Slot `2016-10-07 14:10:00` (free)(duration 10mins)(Child 2)
Slot `2016-10-07 14:20:00` (free)(duration 10mins)
会议2：
Slot `2016-10-07 14:15:00` (free)(duration 5mins)
Slot `2016-10-07 14:20:00` (free)(duration 5mins)(Child 1)
Slot `2016-10-07 14:25:00` (free)(duration 5mins)(Child 2)
会议3：
Slot `2016-10-07 14:10:00` (free)(duration 10mins)
Slot `2016-10-07 14:20:00` (free)(duration 10mins)
Slot `2016-10-07 14:30:00` (free)(duration 10mins)(Child 1)
Slot `2016-10-07 14:40:00` (free)(duration 10mins)(Child 2)
检查时间尚未存储到数组中的最佳方法是什么？如果时间已经存储，那么下次检查时间是否适合其他时间基于时间？
您不必使用我的数据，一个例子会很有用。提前谢谢。
