When running the manual recalculation, it would be nice to have displayed the start and end time, as well as the duration. Particularly in understanding the impact to system performance, it would be helpful for this to be displayed.

This would also be helpful to display so if there are multiple system admins, they can see either 1) the manual recalculation is running; or 2) when the last run was completed and it's status (success or failure).

Similarly, it would also be good to display the same information for the cronjob when enabled. That way, it is easy to see when it ran and the status of the run. This will also be helpful if needing to adjust the overall cron schedule if the job runs longer than anticipated.
