Strange units used for displaying data in charts in Process and Task Dashboard

I found two issues with charts used in Process and task dashboard with kie-wb 7.0:

1) "Tasks By Running Time" is using some strange time unit for task duration.
Compare the task data from the table in the dashboard and the corresponding data displayed in the chart (see screenshot):
In the table the data are shown with minutes/seconds resolution (like 11m 8s) while in the chart I only see a bubble containing average task duration (per process?) and the duration is 32 287 (what unit is that? ) This worked fine in 6.4 (the format used was like 11m 8s)

See screenshots for clarification. Also note in the screenshots: the data displayed by the charts are also rendered into hidden HTML table (which we are using for selenium testing purposes).

2) The following charts are only displaying date data with resolution to year only (as if date was truncated to "yyyy" format only)

• Processes By Start Date
• Processes By End Date
• Tasks By Creation Date
• Tasks By End Date

In 6.5 the charts were using format "dd MMM" which was also not ideal, but at least with day precision.
In my opinion the correct format to be used should include all: year, month and day for date data to be displayed correctly

I'm not sure if this is dashboard issue. It might be the case that this has been caused by migration when removing jBPM Runtime and now the data are fed into dashboard from kie-server?
