> The query profile contains different fragment's and there plan node's event
> timestamps.
>
> Sometimes the expected timestamps from an event are missing, this currently
> throws an exception, hence it stops the rendering of query timeline.
>
> The issue needs to be fixed with some validation of these timestamp event
> labels, without raising an exception.
