Yeah that bothers me too! Here is an example of that from the JIRA
(boldness is mine):
> 18/04/04 09:55:57 WARN AsyncEventQueue: Dropped
com.codahale.metrics.Counter@3348dc4a events from eventLog **since Wed Dec 31
18:00:00 CST 1969.**
At the very least it could be the time that the `AsyncEventQueue` is
instantiated. Simple as changing
[L57](https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/scheduler/AsyncEventQueue.scala#L57)?
```scala
@volatile private var lastReportTimestamp = System.currentTimeMillis()
```
