add date format translation mapping for prefab graph command
Description
There was a request on the mailing list to be able to add a comment to the graph to show a legend line like "From {startTime] To {endTime}".
DefaultRrdGraphService already does that for {startTime} {endTime} and {diffTime} but it (and jrobin) does not have a method to convert the time to a string.
