Management console should write/read time unit and adjust it

The management console is showing me that the average write took 593,036... what? See screenshot

Not only should it mention the unit, but it should adjust it. The JMX API exposes the number of nanoseconds, which is most likely not very relevant... in this case, 593ms might be more relevant... but it should adjust it so that it makes some sense to the reader.

As a side note: averages don't mean much, but that's a different topic
