Sorry for the confusion. Should ahve added more comment on this.
The "REQUIRED" here doesn't mean it has to be set at construction time .It just 
means it should be set at some point before the TelemetryInfo struct is sent 
off.

In any case, I've removed the `EventStats` and moved the start/end time fields 
directly into the TelemetryInfo struct.
