如何解决当用户状态从活动变为离开时，从一系列 UTC 时间戳标记创建时间范围？
我有一系列 json 对象，每个对象都包含特定用户发生事件的时间戳。 JSON 对象 presence 可以是 active 或 away。
我需要找到特定日期的最早 active 时间，然后找到在此时间之后出现的第一个 away 事件，丢弃这 2 个之间的“活动”（或离开）事件时间，并使用它为该特定时间范围创建开始和结束时间。然后我需要继续这样做，直到我拥有当天的所有时间范围。返回的 json 应该是包含当天所有开始（活动）和结束（离开）时间的对象列表。
所以有了这个数据：
[

[{
id: ...,start: 'May 27,2021 3:07:28 pm',end: 'May 27,2021 4:34:14 pm'
},{
id: ...,2021 4:34:27 pm'
end: 'present'
}]
这是我到目前为止所拥有的，但需要一些关于如何按照我需要的方式过滤的指导。有没有一种算法可以查找这样的情况？
