What is the Calendar setting in Clarity? Meaning, do you have just one standard calendar in Clarity set to 8 hrs? If so, Clarity manages the project calendars and I do believe the MSP default settings must match your standard Clarity calendar. If you only have one standard at 8 hrs, have you tried setting up another calendar, associating it to that resource in Clarity and then see if they sync?I might be wrong, but I do know that Clarity will drive the calendar and the settings you mention must match Clarity.Some excerpts from documentation regarding MSP and Clarity Calendar - On the Calendar tab, click “Set as Default� to ensure the d efault start and end time matches the shift schedule on your Clarity standard calendar. Clarity stores and administers the application system data, as well as “charged� project data such as actual hours reported (“actuals�), resource calendars, and cost.
