When using the /datum-delete endpoint on SN, using startDate and endDate works and shows the number of datums that would be deleted in that range of time. However, if you use the /datum-delete/confirm endpoint, passing in the same criteria, it will always fail with a message indicating you should instead use the localStartDate and localEndDate date parameters instead. When I switch to using that, it works fine.

The API docs for /datum-delete/confirm say the same parameters supported in /datum-delete are supported. Either the documentation is wrong and only the local* dates should be used, or the /confirm endpoint is wrong and should allow the absolute dates.
