Instead of outputting "5h 55s 50ms 3us" we'll now output "5h 55.050003s". Also, while outputting the accuracy is configurable. Basically we now try use "dot notation" for all time values > 1min. For >= 1s we use 's' as unit, otherwise for >= 1ms we use 'ms' as unit, and finally 'us'. This should give reasonably values in most cases.
