Google Firebase事件原始数据中关键字“previous_timestamp_micros”的含义是什么？

我已将Google Firebase事件原始数据导出到Google BigQuery . 每个事件都有四个键： name ， params ， timestamp_micros ， previous_timestamp_micros . 例如，我通过 session_start 事件，其下面是从我的数据中提取的事件

"event_dim":[
    {"name":"session_start",
     "params":[
         {"key":"firebase_event_origin",
          "value":{"string_value":"auto"}}],
     "timestamp_micros":"1467374617058000",
     "previous_timestamp_micros":"1467191135684000"}, ...]

键 previous_timestamp_micros 的含义是什么？它是同一用户之前 session_start 的时间戳吗？或者它是同一用户之前事件的时间戳？我检查了数据，似乎两个猜测都是不正确的 .

firebase google-bigquery firebase-analytics

    以下是来自event_dim架构

    timestamp_micros            INTEGER     The timestamp (in microseconds) at which this  
                                        event was logged.   
previous_timestamp_micros   INTEGER     The timestamp (in microseconds) at which this  
                                        event was previously logged.
