Conflict with Scheduler?

I'm not able to get Scheduler (5.x-1.16) to work with Event 5.x-2.x-dev. When I use Scheduler to schedule an event node to be published in the future, the event appears to save correctly, with the correct event start/end dates; but when the event gets published according to schedule, the event's date is gone, and a start of "0 - 12:am" is displayed.

Then when I edit the event, the event's start and end date on the edit form are reset to the current time .

I don't know whether this is a conflict that this dev version of Event has with Scheduler, or whether there's another cause. I don't see an issue like this reported under the Scheduler module.
