I scheduled a deployment of Office and it started 6 hours before the scheduled time.
The time based on: was set to Client time. Commit changes at deadline or during a maintenance window was checked. I have since unchecked it. It seems the application started deployments began soon after I added a bunch of PCs to the device collection associated with the deployment.
I have done other scheduled deployments with the same application and they kicked off at the scheduled time.
Thanks for any help.
